Solutions

Question 1
To find out how much time the boys spent at the cinema, we need to add the time they spent watching each comedy. 3/4 + 1/4 = 1. Therefore, the boys spent 1 hour at the cinema (which can also be written as the fraction 1/1).

Question 2
Step 1: To find the fraction of cupcakes eaten, divide the number of cupcakes eaten by the total number of cupcakes. Step 2: So, the fraction of cupcakes eaten is 8/10. Step 3: To simplify this fraction, we can divide the numerator and denominator by the greatest common factor, which is 2. Step 4: Therefore, 8/10 simplifies to 4/5. Step 5: Hence, the fraction of cupcakes eaten is 4/5.

Question 3
Step 1: Write the fraction as the number of candies Tom took over the total number of candies in the jar. Step 2: Simplify the fraction by dividing both the numerator and the denominator by their greatest common factor. Step 3: The solution is the simplified fraction obtained in Step 2. For the given problem, the solution is: 1/8.

Question 4
The cats originally had 2 1/3 pounds of catnip. They shared 2/3 of a pound, which leaves them with 2 1/3 - 2/3 = 1 2/3 pounds of catnip left to enjoy.

Question 5
Olivia boiled 12 potatoes, which means she added milk 6 times because 12/2=6. To find out how much milk she added, we multiply the number of times she added milk by the amount she added each time. So, 6x3=<<6*3=18>>18 ounces of milk was added to the mashed potato.

Question 6
To determine the fraction of the pizza that Tiffany had left, we first need to find out how many slices she gave away. 7 slices went to Kyle and 4 slices went to Samantha, so she gave away a total of 11 slices. To find out how many slices she had left, we can subtract the number of slices she gave away from the total number of slices, which is 16. This gives us: 16 - 11 = 5. So, Tiffany had 5 slices left. To express this as a fraction of the whole pizza, we can use the formula: number of slices remaining / total number of slices. Plugging in the values we found, we get: 5/16. Therefore, Tiffany had 5/16 of the pizza left.

Question 7
Step 1: Identify the total number of cupcakes on the tray, which is given as 15. Step 2: Identify the number of cupcakes that Amy ate, which is given as 2. Step 3: Divide the number of cupcakes that Amy ate, 2, by the total number of cupcakes on the tray, 15. Step 4: Simplify the fraction obtained in step 3, if possible. Therefore, the fraction of the cupcakes that Amy ate is 2/15.

Question 8
To find the total number of servings of lemon cake Tom gave away, we need to add the fractions of servings he gave to Alex and Lucy. First, we need to find a common denominator, which is 9. Then, we can add the fractions: 3 7/9 + 6 2/9 = 9 9/9 = 10/1. Therefore, Tom gave away 10/1 servings of lemon cake, which can be simplified to 10.

Question 9
To find out how many geese families were left in the lake, we need to subtract the number of families that went to warmer climates from the total number of families present at the lake. Geese families left in the lake = Total number of geese families - number of geese families that went to warmer climates Geese families left in the lake = 80 - 45 So, 35 geese families were left in the lake.

Question 10
To find the fraction of the novels that Maxwell and his mom bought, we need to divide the number of novels they bought by the total number of novels on the shelf. They bought 4 novels out of 20 novels on the shelf. So, the fraction they bought is 4/20, which simplifies to 1/5.

Question 11
To find the total number of bottles required, we need to multiply the number of students by the number of bottles each student needs. So, the school needs to bring 80 x 1.5 = 120 bottles of water.

Question 12
To find the fraction of books Mia borrowed, we need to divide the number of books she borrowed by the total number of books on artists. The total number of books on artists is 30 + 20 = 50. If she borrowed 10 books, the fraction of books she borrowed is 10/50 or 1/5.

Question 13
\frac{5}{8}

Question 14
To find out how many tablespoons of sugar are needed to make 15 cookies, we need to use proportion. We can set up the proportion: 5/20 = x/15, where x is the unknown amount of tablespoons of sugar needed. To solve for x, we can cross multiply and get 20x = 75. Finally, we can divide both sides by 20 and get x = 3.75. Therefore, 3.75 tablespoons of sugar are needed to make 15 cookies.

Question 15
Amanda gave a total of 6+3=9 slices to Ethan and Olivia. Thus, Amanda has 15-9=6 slices left. To find the fraction of the watermelon she has left, we can represent it as a fraction as follows: 6/15 This fraction can be simplified to 2/5. Therefore, Amanda has 2/5 of the watermelon left.

Question 16
To calculate the total number of pizza slices Fred's friends brought, we can start by multiplying the number of friends (8) by the number of slices each friend brought (5). This gives us 40 slices of pizza in total. In addition, each friend brought 4 bags of chips, which is not relevant to the question. Therefore, the answer is 40 slices of pizza.

Question 17
To find the answer, we need to subtract the amount of bones buried from the amount of bones dug up. First, we need to convert both fractions to have the same denominator. The least common multiple of 2 and 1 is 2, so we can rewrite the fractions as 9/2 and 3/2. Subtraction the fractions gives us 6/2 or 3. Therefore, the dogs have 3 bones to chew on now.

Question 18
To find the fraction of the classroom left for the other students to occupy, we need to subtract the fraction representing the parts taken by the one student from the whole classroom. 8/8 - 3/8 = 5/8 Therefore, 5/8 of the classroom is left for the other students to occupy.

Question 19
5/8 of the pie is left for the others.

Question 20
Step 1: Identify the total number of pencils in the box, which is given as 20. Step 2: Identify the number of pencils that John took, which is given as 4. Step 3: Divide the number of pencils John took, 4, by the total number of pencils in the box, 20. Step 4: Simplify the fraction obtained in step 3, if possible. Therefore, the fraction of the pencils in the box that John took is 4/20 or 1/5.
