9+10 ii am struggling really bad plz .

Step-by-step explanation:

9+10=19.

Replace the 0 in the ten with the 9.

So what you would do is you would divide the top number (numerator) by the bottom number (denominator) Like you would normally. So take 3/10 for example you would punch into a calculator 3 divided by 10 or do the work which would be

0.3

and that is how you convert a fraction into a decimal with a denominator of 10

I hope that this helped you. (:
