The number of digits in the coefficient should be exactly the same as the number of significant figures.

When multiplying, the number of significant numbers in the answer should be the same as the fewest significant figures in the problem. Both 13.5 and 3.00 have three significant figures, so the answer will have three significant figures. 13.5 x 3.00 = 40.5 exactly (no need to round).

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 .

A ruler or scale should not be read to less than the smallest graduation. In practice, in-between measurements can be estimated but they are not significant.

I would generally suggest using the most significant digits in the question as a reflection of the level of detail they want. If they wanted more detail (assuming 3.14 represents the constant pi), then they would have listed pi to the significant digits necessary
