Question

Name three decimals with a product that is about 40

Answer 1

16 divided by 40 is 0.40

Answer 2

There are infinite number of triplet of three decimals whose product will be 40.

Let A=1.6

B=2.56

Then ,

`C=(40)/(1.6 * 2.56)\\\\C=9.765625`

Why chosen 1.6 and 2.56 as two numbers because if denominator of fraction has term which contain
`2^a,\text{or}5^b,\text{or},2^a * 5^b`, then the fraction will be terminating decimal.
