Answer:
Round to six significant = 1000.92
Explanation:
Given data:
Given value = 9.9100881×101
Round given value to six significant figures
Solution:
Significant figures:
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.
Zero between the non zero digits are consider significant like 104 consist of three significant figures.
The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
How to round the digits:
First we will look at the six digit of given values.
we will draw a line after six digit then we will look the digit after line.
It the digit after line which is 7th digit is 5 or more than 5 then one will be added to the six digit.
If it it is less than five then six digit remain same.
After this we will add zeros to the right till decimal point.
In given measurement:
9.9100881×101 = 1000.9188981
1000.9188981
Six digit is 1 and 7th is 8 thus 1 is converted into 2.
Round to six significant = 1000.92
