Question

I really suck at math plz help me

Answer 1

155/100 is the answer because 8/10 is really 80/100 so you would add numerators and get 155 so you would slide your 100 as under as your denominator.

Answer 2

You would have to have common demoniators to add.
8/10 can be turn into 80/100 by multiplying the denominator and nominator by ten
75/100+80/100, you add the nominators ONLY, dont change the denominator.
75+80=155

so your answer would be 155/100
