I hope it's good for you

Simplification is 3:5 to 1:5 in the first question, 0.25 to 0.75 in the second question and 1:8 to 0.75 in the third question

Both sides of the same X5, get 3:1
The original formula = 1 / 8:20 / 3 & nbsp; both sides are the same as x24, and the result is 3:160
The original formula is 1 / 8:3 / 4, both sides are the same as X8, and 1:6 is obtained
