Question

Using approximations to 1 significant figure,

estimate the value of
0.482 x 61.22 ÷ 198.01

Answer 1

Step-by-step explanation:

a significant figure is the number of digits in a numerical data (value), typically a measurement, which enhances its degree of accuracy.

Based on the information provided above, we can reasonably infer and logically deduce the following mathematical equation;

By solving the expression in parts

Next, we would divide the expression above as follows;

1806/10 = 180.6.

Answer 2

To estimate 0.482 x 61.22 ÷ 198.01 to 1 significant figure, round each number to one significant figure and perform the calculation, resulting in an estimated value of 0.2.

Step-by-step explanation:

To approximate the value of 0.482 x 61.22 ÷ 198.01 to 1 significant figure, we'll begin by rounding each number to one significant figure. The number 0.482 can be approximated to 0.5, 61.22 can be approximated to 60, and 198.01 can be approximated to 200. Now, using these approximations, we'll perform the calculation step-by-step. First, multiply 0.5 by 60 to get 30. Then, divide 30 by 200 to get 0.15. Finally, since we are required to use one significant figure, we round the result to 0.2.

Therefore, the estimated value of 0.482 x 61.22 ÷ 198.01, using approximations to 1 significant figure, is 0.2.
