Question 1.
Jack has $$\frac{1}{2}$$ of a sandwich. He wants to give it to 4 friends and give each an equal amount. How much of the sandwich will each friend get?

Quantity of sandwich each friend gets = $$\frac{1}{8}$$  or 0.125.

Explanation:
Quantity of a sandwich Jack has = $$\frac{1}{2}$$
Number of friends he gives it = 4.
Quantity of sandwich each friend gets = Quantity of a sandwich Jack has ÷ Number of friends he gives it
= $$\frac{1}{2}$$  ÷ 4
= $$\frac{1}{8}$$  or 0.125.

Question 2.
Tammy has $$\frac{1}{4}$$ of a cucumber. She wants to give it to 3 friends and give each friend an equal amount. How much of the cucumber should each friend get?

Quantity of the cucumber each friend gets = $$\frac{1}{12}$$ or 0.83.

Explanation:
Quantity of a cucumber Tammy has = $$\frac{1}{4}$$
Number of friends she wants to give it = 3.
Quantity of the cucumber each friend gets = Quantity of a cucumber Tammy has ÷ Number of friends she wants to give it
= $$\frac{1}{4}$$ ÷ 3
= $$\frac{1}{12}$$ or 0.83.

Question 3.
Maggie has a pail that can hold 4 gallons of water. If she uses a cup that can hold $$\frac{1}{4}$$ of a gallon, how many cups of water will she need to fill the pail?

Number of cups of water she needs to fill the pail = 16.

Explanation:
umber of gallons of water Maggie has a pail that can hold = 4.
Number of gallons of water she uses a cup that can hold = $$\frac{1}{4}$$
Number of cups of water she needs to fill the pail = Number of gallons of water Maggie has a pail that can hold ÷ Number of gallons of water she uses a cup that can hold
= 4 ÷ $$\frac{1}{4}$$
= 4 × 4
= 16.

Question 4.
Amy has a box that can hold 6 kilograms of sand, If she uses a scoop that can hold $$\frac{1}{5}$$ of a kilogram, how many scoops of sand will she need to fill the box?

Number of scoops of sand she needs to fill the box = 30.

Explanation:
Number of kilograms of sand Amy has a box that can hold = 6.
Number of kilograms of  a scoop she uses that can hold = $$\frac{1}{5}$$
Number of scoops of sand she needs to fill the box = Number of kilograms of sand Amy has a box that can hold ÷ Number of kilograms of  a scoop she uses that can hold
= 6 ÷ $$\frac{1}{5}$$
= 6 × 5
= 30.

Question 5.
Julio solved $$\frac{1}{3}$$ ÷ 5. The quotient is $$\frac{1}{15}$$. Write the equation he can use to check his answer.
Check: he can use:
=> $$\frac{1}{15}$$ × 5 = $$\frac{1}{3}$$.

Explanation:
Equation Julio solved = $$\frac{1}{3}$$ ÷ 5.
The quotient is $$\frac{1}{15}$$.
Check:
Quotient × Divisor = Dividend.
=> $$\frac{1}{15}$$ × 5 = $$\frac{1}{3}$$.

Question 6.
$$\frac{1}{4}$$ ÷ 5 = _____________
$$\frac{1}{4}$$ ÷ 5 = $$\frac{1}{20}$$

Explanation:
$$\frac{1}{4}$$ ÷ 5 = $$\frac{1}{4}$$ × $$\frac{1}{5}$$
= $$\frac{1}{20}$$

Question 7.
$$\frac{1}{3}$$ ÷ 6 = _____________
$$\frac{1}{3}$$ ÷ 6 = $$\frac{1}{18}$$

Explanation:
$$\frac{1}{3}$$ ÷ 6 = $$\frac{1}{3}$$ × $$\frac{1}{6}$$
= $$\frac{1}{18}$$

Question 8.
$$\frac{1}{2}$$ ÷ 7 = _____________
$$\frac{1}{2}$$ ÷ 7 = $$\frac{1}{14}$$

Explanation:
$$\frac{1}{2}$$ ÷ 7 = $$\frac{1}{2}$$ × $$\frac{1}{7}$$
= $$\frac{1}{14}$$

Question 9.
6 ÷ $$\frac{1}{4}$$ = _____________
6 ÷ $$\frac{1}{4}$$ = 24.

Explanation:
6 ÷ $$\frac{1}{4}$$ = 6 × 4
= 24.

Question 10.
4 ÷ $$\frac{1}{5}$$ = _____________
4 ÷ $$\frac{1}{5}$$ = 20.

Explanation:
4 ÷ $$\frac{1}{5}$$ = 4 × 5
= 20.

Question 11.
5 ÷ $$\frac{1}{2}$$ = _____________
5 ÷ $$\frac{1}{2}$$ = 10.

Explanation:
5 ÷ $$\frac{1}{2}$$ = 5 × 2
= 10.
