Question

It rained 0.84 inches on Saturday and 0.8 inches on Sunday. How much did it rain on Saturday and Sunday combined?

Answer 1

1.64 is the answer. My proof calculator

Answer 2

1.64

Explanation:

The first step to do is to line up the decimal points. We have to add a zero to 0.8 so that the decimal points will align (this does not change the value).

0.84

+0.80

Then bring down the decimal point into the answer column, and add like normal.

0.84

+0.80

1.64

Hope this helps!
