Troy calculated that 0.095 x

4,689,189.5 = 445,473. Is Troy's
calculation reasonable? Show how
you can use estimation to decide.​

Answer 1

yes, it is reasonable.

Explanation:

0.01 is close to 0.095

so 0.1 times something is the same as that thing divided by 10, so 4,689,189.5 divided by 10 is 468,918, which is close enough.
