Jing is helping the kindergarten teacher put together bags of crayons. Each bag has 4 crayons, and 1/4 of the crayons in each bag are green. What fraction of the crayons in 3 bags are green? (A.) 3/12 (B.) 3/4 (C.) 4/3 (D.) 12/3

A)  

Step-by-step explanation:

Given:

Jing is helping the kindergarten teacher put together bags of crayons.

Each bag has 4 crayons, and 1/4 of the crayons in each bag are green.

What fraction of the crayons in 3 bags are green?

Solution:

1 bag contains number of crayons = 4

1 bag contains number of green crayons =

Total number of bags = 3

Total number of crayons in 3 bags = 4 3 = 12

1 bag contains number of green crayons = 1

Total number of green crayons in 3 bags = 1   3 = 3

Fraction of the green crayons out of total = 3 out of 12 =

Therefore, fraction of the crayons in 3 bags are green are  

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
