Question

Estimate the sum by rounding each fraction to 0, 1/2, or 1.8/9 + 4/12

Answer 1

The fraction 8/9 is closer to 1 than to 1/2, so let's round it to 1

The fraction 4/12 is closer to 1/2 than to 0, so let's round it to 1/2

Then, adding each rounded value, we have:

`1+(1)/(2)=(2)/(2)+(1)/(2)=(3)/(2)`

So the result is 3/2 (or 1 1/2).
