Isaac finished 8 out of 10 homework problems phil has finished 3/5 ,who finished the most? how many more do he do?

Isaac finished 2 more questions.

Step-by-step explanation:

If Isaac finished 8 out of 10 (8/10), and Phil finished (3/5), we can figure out who finished more by finding the common denominator of the two numbers.

To find the common denominator, we can see that to get to 10 we need to multiply 5 x 2. So multiply 3/5 by 2/2 to get 6/10.

Now compare 8/10 to 6/10. We can see that Isaac finished 2 more questions than Phil because 8 - 6 = 2.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
