Add a to the product of a number and its reciprocal to get 4 / 5 of 7, and find the reciprocal of A

If the product of a number and its reciprocal is 1, then a is 32 / 7, and its reciprocal is 7 / 32

If the product of a number and its reciprocal plus x equals seven thirds, what is the reciprocal of X?

That is, 1 + x = 7 / 3
X = 7 / 3-1
X = 4 / 3

The ratio of a to B is (): () and the ratio is ()?

The ratio of a to B is (5): (6), and the ratio is (5 / 6)
[analysis]
A = (5 / 6) B
A / b = 5 / 6
The ratio is 5 / 6

A is 0.4, B is 35, and the ratio of a to B is 1_ The ratio is_ ．

4:35 = (0.4 × 10 △ 2): (35 × 10 △ 2) = 2:30.4:35 = 2:3 = 23

The ratio of the two numbers is 5 / 6. The ratio of the two numbers is ()

The ratio of the two numbers is 5 / 6. If the two numbers expand three times at the same time, their ratio remains unchanged or (5 / 6)

The ratio of number a to number B is 3:2, the ratio of number B to number C is 5:6
The ratio of number a to number B is: 3: the ratio of number B to number C is 5: the ratio of number a to number C is ()
Sorry, there was a mistake

A: B = 3:2 times 5
B: C = 5:6 times 2
A: C = 5:4
It seems that the question is wrong. It should be a better than C

The ratio of number a to number B is 2:3, the ratio of number B to number C is 6:5. The ratio of number B to number C is ()

The ratio of number a to number B is 2:3, the ratio of number B to number C is 6:5, and the ratio of number a to number C is (4:5)
A: B: C = 2 × 2:6:5 = 4:6:5;

The ratio of number a to number B is 3:4, the ratio of number B to number C is 5:6, and the ratio of number a to number C is? (formula)

The ratio of number a to number B is 2:3, the ratio of number B to number C is 5:6, what is the ratio of number a to number C

Number A: number b = 2:3 = 10:15
Number B: number C = 5:6 = 15:18
So number A: number B: number C = 10:15:18
Number A: number C = 10:18 = 5:9

2 / 3 of a is equal to B. the ratio of a to B is (), and the ratio is ()

A: B = 1:2 / 3
=3: 2 (minimalist)
=1.5 (ratio)

Add a to the product of a number and its reciprocal to get 4 / 5 of 7, and find the reciprocal of A
