What is 3 over 4 plus 9 over 8

15/8 or 1 7/8

Step-by-step explanation:

1. you have to have the same denominator (bottom number)

2. find the multiples of four (4,8,12,16,20 ...)

3. find the multiples of eight (8,16,24,32 ...)

4. take the multiple that they have in common (8)

5. four time two equals eight so multiply the fraction 3/4 by two

6. eights times one equals eight so multiply the fraction 9/8 by one

7. take the final products and add them together

I think it's 1.875 I believe
