Hi there!
To solve this is pretty simple - To put this into a decimal, we divide the numerator by the denominator. But first, I like to simplify this down to its simplest form.
It would be 4/10.
4 ÷ 10 = 0.4
There's your decimal answer! 0.4!
If you wanted to make this into a fraction, however, you would multiply your decimal by 100 to make 40%.
Hope this helps! :D
