Write and solve an equation to show the answer.

Explain when to use division and when to use multiplication to solve an equation. Give examples to support your answer

Answers

Answer 1

Answer: 1,796

Step-by-step explanation:

We are given that : At the chicken ranch this morning there were 7,149 chicks.

i.e. The number of new chicks before today = 7,149

Later today some more chicks hatched. now the ranch has 8,945 chicks.

i.e. The number of new chicks after today = 8,945

Then, By Subtraction operation

Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )

= 8,945- 7,149 = 1,796

Therefore , the number of new chicks hatched today = 1,796
