danjs · Answer

i would multiply everything by 5 first to clear out the fractions

danjs · Answer

or, just add 3 and 2/5ths to 8 and 1/5th

I kiddna don't how to I know it's gonna be 17/5 + 41/5 which is 58/10 right?

@DanJS

danjs · Answer

since b is already by itself, and the denominators are the same on those mixed numbers, you can just add 3 2/5  to both sides of the equation

danjs · Answer

b = (8+3) + (1/5 + 2/5)

anonymous · Answer

11 3/5?

danjs · Answer

yeah, you had the improper fractions above right,... you said

"it's gonna be 17/5 + 41/5 which is 58/10 right?"

just the 58/10 should still be the same denominator of 58/5 which is the same as 11 3/5

danjs · Answer

that is right, 11 3/5  or in improper form 58/5
