TEKS 5.3I Worksheets — Grade 5 Represent and solve multiplication of a whole

Sofia is organizing a community clean-up event at the local park. If she has 12 garbage bags and each bag can hold 3/4 of a cubic foot of trash, how many cubic feet of trash can Sofia collect in total?

1. 9 ✓
2. 10
3. 8
4. 7

Why: To find the total cubic feet of trash Sofia can collect, multiply the number of garbage bags by the capacity of each bag: 12 * (3/4) = 12 * 0.75 = 9 cubic feet. Therefore, the correct answer is 9.

Sofia is having a picnic at Galveston Bay. She has 6 loaves of bread, and each sandwich requires 1/2 of a loaf. How many sandwiches can Sofia make with the bread she has?

1. 12 ✓
2. 3
3. 6
4. 9

Why: To find out how many sandwiches Sofia can make, you need to divide the total number of loaves by the fraction of a loaf needed for each sandwich. So, we calculate 6 ÷ (1/2). Dividing by a fraction is the same as multiplying by its reciprocal, which means we can rewrite the equation as 6 × 2/1. This gives us 12 sandwiches. Therefore, the correct answer is 12.

Zara had a collection of 80 colorful marbles. She decided to give away 1/4 of her marbles to her friend. How many marbles did Zara give to her friend?

1. 20 ✓
2. 15
3. 25
4. 30

Why: To find out how many marbles Zara gave to her friend, we need to calculate 1/4 of 80. This is done by multiplying 80 by 1/4, which equals 80 * 1/4 = 20. Therefore, Zara gave away 20 marbles.

Santiago is preparing a batch of traditional German schnitzel for a family gathering. The recipe requires 3/4 of a cup of breadcrumbs for each schnitzel. If he plans to make 4 schnitzels, which expression best represents the total amount of breadcrumbs Santiago will need?

1. 3/4 * 4 ✓
2. 3/4 + 4
3. 3/4 / 4
4. 3 * 4

Why: To find the total amount of breadcrumbs needed, Santiago must multiply the amount needed for one schnitzel (3/4 cup) by the number of schnitzels he plans to make (4). Thus, the correct expression is 3/4 * 4. This shows how to represent multiplication of a whole number and a fraction.

Leila is making tacos for a family gathering in San Antonio. She has a pack of tortillas that contains 40 tortillas. If each taco requires 1/4 of a tortilla, how many tacos can Leila make with the tortillas she has?

1. 160 ✓
2. 100
3. 120
4. 80

Why: To find out how many tacos Leila can make, we need to multiply the total number of tortillas (40) by the reciprocal of the fraction of a tortilla needed for each taco. Since each taco uses 1/4 of a tortilla, the reciprocal is 4. So, we calculate 40 × 4 = 160. Therefore, Leila can make 160 tacos.

Mateo is planting bluebonnets in his garden. He wants to plant 3/4 of a bag of bluebonnet seeds in each of his 4 flower beds. How many bags of bluebonnet seeds will Mateo use in total?

1. 3 ✓
2. 2
3. 4
4. 1

Why: To find the total bags of bluebonnet seeds Mateo will use, multiply the number of flower beds by the fraction of a bag used per bed. That is, 4 * 3/4 = 12/4 = 3. Therefore, Mateo will use a total of 3 bags of bluebonnet seeds.

Zara is baking cookies for her family's gathering. She has a recipe that requires 2 cups of flour. If Zara wants to double the recipe to make more cookies, how many cups of flour will she need in total?

1. 4 cups ✓
2. 3 cups
3. 2 cups
4. 5 cups

Why: To find out how many cups of flour Zara needs to double her recipe, you multiply the original amount of flour by 2. Since the recipe calls for 2 cups of flour, doubling it means 2 × 2 = 4 cups. Therefore, Zara will need a total of 4 cups of flour.

Mario is helping his family at their farm in the Edwards Plateau. They collected 3/4 of a bushel of peaches to sell at the local market. If they sold 2/3 of the peaches they collected, how many bushels of peaches did they sell?

1. 1/2 ✓
2. 1/4
3. 1
4. 2/3

Why: To find out how many bushels of peaches Mario's family sold, first calculate 2/3 of the 3/4 bushel collected. Multiply: (2/3) * (3/4). This equals 6/12, which simplifies to 1/2. Therefore, they sold 1/2 of a bushel of peaches.
