Answer:
130
Step-by-step explanation:
When finding 10% of a number just move the decimal over to the left once.
For example if your number is 150 you want to move the "decimal" over to the left once:
150 is the same as 150.0 so getting 10% gives you: 15.0
This means if you want to go the other way and find the number after already having 10% of the number then you want to move the decimal to the right. In this case:
13.0 would become 130.
13 is 10% of 130
