Question

0.51 + 6.1 = 6.61 because 0.51 is precise to the hundredth digit, so theanswer must also be rounded to the nearest hundredth.A. TrueB. False

Answer 1

When two decimal numbers are added, the result is precise to the one that has the least precision.

For example,

0.51 + 6.1

Here 0.51 is precise to the hundredth place and 6.1 is precise to the tenth place.

So, the result will be precise to the tenth place since this was the least precision in the operation.

0.51 + 6.1 = 6.6
