Question

Simplify each expression 2x-5y. If x=2/3 and y=1/4

Answer 1

`(1)/(12)`

Explanation:

`2x-5y=\\\\2((2)/(3))-5((1)/(4))=\\\\(4)/(3)-(5)/(4)=\\\\(16)/(12)-(15)/(12)=\\\\(1)/(12)`

Answer 2

1/2

Explanation:

2x - 5y

2(2/3) - 5(1/4)

(2/1 x 2/3) - (5/1 x 1/4)

(4/3) - (5/4)

(4/3 x 4/4) - (5/4 x 3/3)

16/12 - 15/12

1/12
