Question

Is this correct? (Last question) Btw giving BRAINLIEST (I'll try to) if you know little who little lad is BUT you have to say what he says!!

Answer 1

The expression $2.4 \times 7$ can be estimated by $2 \times 7$, so the answer would be roughly 14 here. I'm not sure where you got that '1' from.

Directly below that problem, we have the expression $63.2 \times 0.78$ which can be estimated by computing $63 \times 1$ which simplifies to 63. The '1' is from rounding to the nearest whole number.

Other than that, everything else looks correct on your worksheet.
