Mrs. Williams combined 3 ½ cups of peat moss, 5 ¼ cups of compost , and 6 ¾ cups of fertilizer to make plant food for her roses. She evenly distributed the plant food among 4 rose bushes. How many cups of plant food were used for each rose bush?

3 7/8 cups plants food

Step-by-step explanation:

peat moss = 3 ½ cups

compost = 5 ¼ cups

fertilizer = 6 ¾ cups

Total mixture = peat moss + compost + fertilizer

= 3 ½ cups + 5 ¼ cups + 6 ¾ cups

= 7/2 + 21/4 + 27/4

= 14+21+27/4

= 62/4

Total mixture = 62/4 cups

She evenly distributed the plant food among 4 rose bushes

Each rose bush uses = Total mixture / number of rose bushes

= 62/4 ÷ 4

= 62/4 × 1/4

= 62/16

= 3 14/16

= 3 7/8 cups plants food

Each rose bush uses = 3 7/8 cups of plants food
