To estimate 49 × 12 to one significant figure, round 49 to 50 and 12 to 10, then multiply to get an estimated product of 500.

The question asks to estimate the answer to 49 × 12 by first rounding each number to 1 significant figure. First, we round the numbers: 49 rounds to 50 and 12 rounds to 10. Then, we multiply the rounded numbers: 50 × 10 equals 500. The estimation using numbers rounded to one significant figure suggests that the answer to 49 × 12 is approximately 500.

To estimate the product of 49 and 12 by rounding each number to 1 significant figure:

49 is already a number with 2 significant figures.

12 can be rounded to 10 because when rounded to 1 significant figure, the value is closer to 10 than to 20.

Now, we can estimate the product:

49×12≈50×10=500.So, by rounding each number to 1 significant figure, the estimate for

49×12 is approximately 500.
