Question

What is the simplified form of 4/3y - 5/y^2

Answer 1

a) 5y-12/3y^2
b) 4y-14/3y^2
c) 12-5y/3y^2
d) 15-4y/3y^2

Answer 2

@sarahusher this is just like the other one right?

Answer 3

well firstly we know that:
\[\frac{ a }{ b } - \frac{ c }{ d } = \frac{ a }{ b } + \frac{ d }{ c }\]
then:
\[\frac{ a }{ b } + \frac{ c }{ d } = \frac{ a*d + c*b }{ b*d }\]
so
\[\frac{ 4 }{ 3y } - \frac{ 5 }{ y ^{2} } = \frac{ 4 }{ 3y } + \frac{ y ^{2} }{ 5 }\]

yes! @danny562 , this is exactly like the other one!

Answer 4

(4)/(3y)-(5)/(y^(2))
= (4y)/(3y^2) - 5(3) / (3y^2)
= (4y-15) / (3y^2)
