So to solve for this, since we have here, addition and subtraction, right? so what you have to remember is that in addition or subtraction, we have to look for the term, having the smallest number of decimal places, and then round up the final answer to the same number of places.
00:24
Okay, so for a, we have 2 .35, 2 .45, and 7 .2 things.
00:28
So we have the same decimal places for the three terms so that's two decimal places so our final answer will be in two decimal places also so that's 12 .03 and then for b we have again two decimal places in three numbers so again our answer will be in two decimal places so we have 4 .807 and then for c we have 3 .725, 3 .445, and 3 .72.
01:06
Which has the smallest number of decimal places here.
01:09
We have 3 .72.
01:10
So we have two decimal places for this, and that means our final answer should have two decimal places.
01:18
All right.
01:19
So for c, this will be 10 .92.
01:23
All right.
01:24
And then for d, we have 41 .57...
