Question

Estimate five-elevenths times thirty-one.

3

one-third

7

fifteen

Answer 1

The question calls for an estimate. So we could modify the two values slightly to make the calculation easier. Notice that the values of the four choices are not close together.
Lets make 5/11 a half (5/10 = 1/2) and make thirty-one 30 instead.
Half of thirty is fifteen. Hope this helps you.
