Question

Estimate the product by rounding each number to the nearest 10. Then compute the product. Is your estimate an underestimate or overestimate? 74 x 548

Answer 1

To estimate the product 74 x 548 by rounding each number to the nearest 10:

- **74** rounds to **70**.
- **548** rounds to **550**.

Now, we compute the estimated product:

\[
70 \times 550 = 38500
\]

Next, let's compute the actual product of 74 and 548:

\[
74 \times 548 = 40672
\]

Now, we compare the estimated product (38500) with the actual product (40672).

Since 38500 is less than 40672, our estimate is an **underestimate**.
