Final answer:
The estimate of 0.32 x 0.073 after rounding both numbers to one significant figure is 0.02 or 0.03. It depends on situation.
Step-by-step explanation:
To estimate 0.32 x 0.073 by rounding both numbers to one significant figure, we first round each number to its most significant digit. 0.32 rounds to 0.3 because the '3' is the first non-zero digit and has the highest place value. Similarly, 0.073 rounds to 0.07 for the same reason, the '7' being the most significant digit. With these rounded values, the multiplication becomes:
0.3 x 0.07 = 0.021
However, since we want our final answer to have only one significant figure as well, we round 0.021 to 0.02. Therefore, the estimated product of 0.32 and 0.073 when both are rounded to one significant figure is 0.02.
Or To estimate 0.32 x 0.073 by rounding both numbers to one significant figure, you first need to round each number individually. 0.32 rounded to one significant figure is 0.3 and 0.073 rounded to one significant figure is 0.1. Then, multiply the rounded numbers together: 0.3 x 0.1 = 0.03. Therefore, the estimate of 0.32 x 0.073, rounded to one significant figure, is 0.03.
