Answer:
Each of
12.9 * 0.9
and
0.62 * 1.5
gives an overestimate.
Step-by-step explanation:
Let us check the value for each of the given products to see which one has a higher value after rounding to the nearest whole number, than its exact value.
11.6 * 9.5
= 110.2
= 110 (rounded)
4.49 * 8.3
= 37.267
= 37 (rounded)
12.9 * 0.9
= 11.61
= 12 (roounded) THIS GIVES AN OVERESTIMATE
0.62 * 1.5
= 0.93
= 1 (rounded) THIS GIVES AN OVERESTIMATE
8.46 * 7.38
= 62.4348
= 62 (rounded)
Therefore, each of
12.9 * 0.9
and
0.62 * 1.5
gives an overestimate.
