ok
OpenStudy (ilovecake):
Do I add the numbers?
OpenStudy (anonymous):
we need first find a common denominator..a number both 5 and 4 go into evenly..20 seems about right
so we need to multiply the whole first fraction by 4 to make the denominator 20...and the whole second fraction by 5 to make that denominator 20
OpenStudy (ilovecake):
So C is not one of the right answers
OpenStudy (anonymous):
4/4x3/5+5/5x3/4 this will come out 12/20+15/20 whcih will equal............. Hint add 15/20 + 12/20 and it will give you your answer

OpenStudy (anonymous):
3/5 + 3/4 = 12/20 + 15/20 = 27/20 (total juice)
3/(27/20) = 1/ (x) --- 3 servings to 27/20 juice = 1 serving to x juice
cross multiply
(3)(x) = (27/20)(1)
3x = 27/20 -- divide by 3
x = (27/20) / 3
x = 27/20 * 1/3
x = 27/60 which reduces to 9/20
OpenStudy (anonymous):
so your answer is 9/20 ;)
OpenStudy (ilovecake):
Ok I understand it now thanks so much :)
