How to do Fraction problems?

Question

3/5 (times) 2/3 (times) 5/2

1/2 + 3/7 - 4/3

for the first one I got 30/30 or 1

and for the second one I got -17/42

Answer 1

Yea thats correct don't underestimate yourself

Answer 2

for the first one, you just multiply all the numerators and all the denominators.

3*2*5/5*3*2  note, the numbers are all the same so the answer is 1

For the second one, you have to get find the lowest common denominator and add the numerators.  LCD = 42

21+18-56/42

-17/42

Answer 3

= 3*2*5/(5*3*2) = 30/30 = 1 You are right

= 21/42 + 18/42 - 56/42 = -17/42 You are right again
