Question

Why is estimating not as helpful when multiplying very small numbers such as 0.007 and 0.053?

Answer 1

Because estimating does not make it exact. If you need to plug 0.007 into an equation (for example if x=0.007, 15x-1= -0.895) it will not be exact.

Answer 2

Answer and Explanation:

Given : Numbers 0.007 and 0.053.

To find : Why is estimating not as helpful when multiplying very small numbers ?

Solution :

Estimating means round to an integer with using significant figures.

Estimating for any number with only one significant figure is that number.

So, If we estimate the number 0.007 then it is 0.007 not 0.

If we estimate the number 0.053 then it is 0.05 or 0.55.

It depends on the other numbers in the product they can change the value of the product.

Therefore, On multiplying very small number estimating is not so useful.
