Question

In 3-14, estimate each product. 6. 8.02 x 70 5. 9.66 x 0,46 4. 345 x 5.79 3. 19.3 x 6

Answer 1

Multiplying the estimated numbers gives you quick and easy approximate results:

8.02 x 70 is approximately 560, 9.66 x 0.46 is about 5, 345 x 5.79 is around 2070, and 19.3 x 6 is roughly 120.

Step-by-step explanation:

To estimate each product, one can round the numbers to their nearest whole number or to a simpler decimal form to make the multiplication easier. Here are the estimations:

1. 8.02 ≈ 8 and 70 is already a whole number, so 8 x 70 = 560.
2. 9.66 ≈ 10 and 0.46 ≈ 0.5, hence 10 x 0.5 = 5.
3. 345 is a whole number and 5.79 ≈ 6, therefore 345 x 6 = 2070.
4. 19.3 ≈ 20 and 6 is a whole number, so 20 x 6 = 120.
