Add the following fractions.
3/8 + 5/12 =

for 3/8 you can times by 12 to make 36/96

for 5/12 you can times by 8 to make 40/96

now that they have the same denominators (bottoms), you can add them to make

36/96 + 40/96 =76/96

simplified

= 38/48

=19/24

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

the two may have that, even a breakdown is probably offered
