Answer 2

Answer:

Step-by-step explanation:

0.45 bar means 0.45454545454545

0.44 bar means 0.44444444444444

Since there are no carry you can simply add 45 and 44 and you will get

0.89 bar or 0.8989898989898989

But the actual way to solve is to first convert it into a fraction.

We can write and repeating and terminating number in the form of x/number of 9 would be the numbers in the decimal before they repeat

In this case, it is 2 because 45 and 44 have 2 digits.

So we get,

45/99 + 44/99 = 89/99

Since 89 has 2 digits we can write this as 0.89 bar
