Homework help...Last question: Estimate the product of 15.217 × 9.54. Round each number to the nearest whole number.

Answer 1

I rounded it to 150.

You could round 15.217 down to 15 and 9.54 up to 10 and then multiply 15 x 10 = 150. But you could also multiply 15.217 x 9.54 to get 145.17018 and round that up to 150 because any number that ends with 5 or higher rounds up.
