a/2+ a/3= 5 .
A)2
B)6
C)3
D)5
E)30

Answer 1

y wont this thing do fractions

Answer 2

it will.... 2/3....do it like that

Answer 3

\[\frac{ 2 }{ 3 } + a =5?\]

Answer 4

oh.

Answer 5

try to find a least common denominator for all the terms. And then you can isolate the a.

Answer 6

a/2 + a/3 = 5 --- multiply everything by the common denominator of 6
3a + 2a = 30
5a = 30
a = 6

Answer 7

LCD would be 30.

Answer 8

what?? is that even english?? lol i dont speak math can you dumb it down for me please

Answer 9

my computer just froze

Answer 10

if you have an equation with fractions, and you want to get rid of the fractions, multiply everything in the equation by the common denominator.

a/2 + a/3 = 5 (or 5/1).....now the common denominator of 2,3, and 1 is 6. So multiply everything by 6.
6(a/2) + 6(a/3) = 6(5) -- just to let you know, a/2 is the same as (1/2)a and a/3 is the same as (1/3)a
6(1/2)a + 6(1/3)a = 6(5)
6/2a + 6/3a = 30
3a + 2a = 30
5a = 30 -- divide both sides by 5
5a/5 = 30/5
a = 6
