@iGreen

Answer 2

Okay.

Original Problem: 1 3/7 * 5 4/5 = 8.28571429

Estimate: 1 1/2 * 6 = 9

So his estimate got 9, and the real solution is approximately 8.29.

So did he overestimate or underestimate?

Answer 3

under

Answer 4

Is 9 bigger than 8.29 or smaller?

Answer 5

oh sorry i meant over LOL

Answer 6

Yep, over is correct..his estimate should be closer to 8 for it to be considered a 'close estimate'.

Answer 7

ok thanks @iGreen
