Fraction Help?

Question

Can someone plz help me with these 3 problems.... I really appreciate it thanx....

1) 77x/3 divided by 2/15

2) 1/6x divided by 5/x^2

3) 30x/83 times 47/15

thanx...im kinda stuck on these 3

Answer 1

1)

(77*x/3) / (2/15) =
(77*x/3) * (15/2) =
(77*15*x) / (3*2) =
(77*5*x) / 2 =
(385*x) / 2

2)

[1/(6*x)] / [5/(x^2)] =
[1/(6*x)] * [(x^2)/5] =
[1/(6*x)] * [(x^2)/5] =
(x^2) / (5*6*x) =
x / (5*6) =
x / 30

3)

(30*x / 83) * (47/15) =
(30*47*x) / (83 * 15) =
(2*47*x) / 83 =
94*x / 83
