Is this right??

10 + 7 = 17/100 = 41.2 %

100 + 92 = 192/100 = 1.92 %

15 + 13 = 28/100 = 1.25 %

28 + 22 = 50/100 = .5%

• Math percentages -

This is right.
192/100 = 1.92 %

The others are wrong.

Remember to divide the numerator by the denominator and then multiply by 100.

These can you write them out for me?

100 + 92 = 192/100 = 1.92 %

15 + 13 = 28/100 = 1.25 %

28 + 22 = 50/100 = .5%

I went through them and still came out with these answers? So confused now. I udnerstand what you mean, but it comes out the numerator so I thought they were right? Can you explain each?
