If 12 is subtracted from 1/10 of a certain number and the answer is 13 what is the number?
Can anybody help?

Try drawing a function machine or a sum with an empty box.
The trick is to work from back to front, in this case.
So, 13 equals (a number divided by ten) minus 12.
So 13=25-12, so 13=250/10-12. So 250?
Did I get the right answer?
Where is G55 when you need some maths help.

We do not know what the number is, so make it as X
(1/10 of X) -12 = 13
(1/10 of X) = 25
Therefore X = 250
Hope this helps
