It is known that a multiplied by two-thirds equals B multiplied by three-quarters, and four fifths of B equals C multiplied by five sixths (a, B, C are not zero), then a: C equals?:

It is known that a multiplied by two-thirds equals B multiplied by three-quarters, and four fifths of B equals C multiplied by five sixths (a, B, C are not zero), then a: C equals?:

75 to 64

Simplify the integer ratio: 4 / 5 to 4 / 7 to 3 / 4
emergency

Four fifths to four sevens, the denominator 5 and 7 multiplied by 35, equal to 28 to 20, and then reduced, divided by 4, equal to 7 to 5
Three to three-quarters simplification: first, turn three-quarters into a decimal of 0.75, use 0.75 * 20 = 15, 3 * 20 = 60, then simplify, divide by 15, equal to 1 to 4

Three quarters * 5 means () two fifths * seven thirds means ()

1-5 times of 3 / 4
2-3 / 7 of 5 / 2
Note: A / b = a of B

It is known that three fourths is equal to a, and B is equal to a tenth

Three quarters equals a, B equals a tenth
3/4=A/10
It can be found that a = 7.5
A/B=3/4
Even if 7.5/b = 3 / 4
We can get b = 10
So a = 7.5, B = 10
