21,600 using only four significant figures is still 21,600.

There are 3 significant figures

Significant figures are calculated using various rules.ÊAll non-zero numbers are significant and all zeros that are to the right of the decimal point as well as at the end of a number are significant.ÊTherefore, 1.050L has 4 significant figures.

The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.

It isn't clear what the question is. If you are supposed to multiply or divide, and if by "signification figures" you mean significant digits, do the multiplication (or division), then round to three significant digits - since the least-precise of the numbers only has three significant digits.

86.346 +54.43 9.5 _______ 150.276 Now after we round the number and write it in significant figures , so it should look like this; 150 why? because when we need to round a number using the significant figures , we must look for the smallest significant figures which is 9.5 .

Because otherwise you are using figures which imply an accuracy that cannot be justified.
