Question

By rounding to one significant figure estimate 798/8*41

Answer 1

Step 1: 798/ 8= 99.75

Step 2: 99.75 * 41 = 4089.75

The first significant figure is the first non-zero digit in a number. Therefore the first significant figure in 4089.75 is 4.

If the number following the value that you are rounding to (in this case, the first significant figure ie 4) is greater than or equal to 5, round up the value, ie add 1 to the number. Otherwise round down to the nearest whole number.

Since the number following the significant digit, 4, is zero we therefore round down the number.

Resulting in:

4000.

Therefore, your answer is 4000
