Question

Keira divided 123.52 by 3.2 and got 38.6. Without using a calculator, how could she check to determine if her answer is reasonable?

Answer 1

Answer:

Keira could use estimation to check her answer. 123.52 is about 120 and 3.2 is about 3. And 120 divided by 3 is 40. This is close to her answer, so it is reasonable

Answer 2

Answer: 38.6

Step-by-step explanation:

you could take the 123.52 and the 3.2 and multiply them both by 100                

( 12352 divided by 320 )

and you would get the same answer as 123.52 divided by 3.2

I hope this makes sense :)
