a) How many rice needed to make half the rice???
b) How much rice is needed to make two and one half times the recipe???

Answer 1

A) 7/8 cups B) 4 3/8 cups

Explanation:

1 3/4 = 7/4

7/4 cut in half is 7/8

7/4 doubled is 7/2

7/2 = 28/8

28/8 + 7/8 = 35/8

35/8 = 4 3/8

Answer 2

• a) 7/8 cups
• b) 4 3/8 cups

Explanation:

Given

Full recipe = 1 3/4 cups of rice

• 1 recipe ⇒ 7/4 cups

a) half of the recipe

• 1/2 recipe ⇒ 1/2*7/4 = 7/8 cups of rice

b) 2 and one half time the recipe

• 2 1/2 recipe = 5/2 ⇒ 5/2 * 7/4 = 35/8 = 4 3/8 cups of rice
