To solve the equation: 3 / 4 X-60 times 2 / 5 = 15 x: 5 / 21 = 20 / 72 / 5 x = 2 / 3 This is the symbol of ratio

To solve the equation: 3 / 4 X-60 times 2 / 5 = 15 x: 5 / 21 = 20 / 72 / 5 x = 2 / 3 This is the symbol of ratio

solve equations:
Three quarters X-60 times two fifths = 15
0.75x-24=15
0.75x=24+15
0.75x=39
x=39÷0.75
x=52
10: Five out of twenty = seven out of twenty
x=7/20x5/21
x=1/12
Five out of twelve x = two out of three
x=2/3÷5/12
x=8/5

Solve the equation 3 / 4: 2 / 3 = x: 6

2/3 x=3/4*6
x=27/4

Solve the equation in brackets (x + 1 / 3) / / 3 / 4 = 2 / 3,

(x + 1 / 3) divided by (3 / 4) = 2 / 3
Both sides of the equation are multiplied by (3 / 4)
x+1/3=1/2
The result of the transfer is as follows:
x=1/2--1/3
=3/6--2/3
x=1/6.
