Question

The ratio of duck eggs to chicken eggs in an egg store is 2:7.If there are 312 duck eggs in the store.how many chicken eggs are there?

Answer 1

Answer:

x = 1,092

Step-by-step explanation:

Duck eggs : chicken heads =

2 : 7

Number of duck eggs = 312

Number of chicken eggs = x

Duck eggs : chicken heads = 312 : x

Equate both ratios

2 : 7 = 312 : x

2/7 = 312/x

Cross product

2 * x = 7 * 312

2x = 2,184

x = 2,184 / 2

= 1,092

x = 1,092
