Answer: Not quite sure, but maybe the answer is 10.
Explanation:
First of all, you need to solve 10.80 ÷ 1.35.
You can't instantly solve it the way it is, so you need to move the decimal from 1.35 two places.
This will give you 135.
You need to do the same with 10.80. We would move the decimal two places because whatever we do with the first decimal, we should do to the second. This will give us 1080.
Now we can divide semi-easily.
1080 ÷ 135
Sine 135 does not fit in the first three, you need to move on to the next numbers. This will leave us with the entire number to divide by itself. In this case, we multiply till we get the answer.
At first, you should go with what you think will be the answer. In this case, I thought it would be × 5, but was wrong. I ended up trying 135 × 8 and was right.
My answer was 8 so, I simply rounded and got 10 because 5 or more raises the score.
I hope I was right. lol-
