Question

9. Five-sevenths of a number is equal to 40% of another
number. What is the ratio of the first number to the
second one?​

Answer 1

Answer:

Let the two numbers are x and y

40% of x = 40x/100 = 0.40x

According to statement 40% of a number is equal to two-third of another number,

0.40x = 2y/3

Cross multiplication

2y = 0.40x × 3

2y = 1.2x

x/y = 2/1.2

x/y = 20/12

x/y = 5/3

The ratio of first number to the second number is 5: 3

Answer : The ratio of first number to the second number is 5: 3

Answer 2

Answer:

Ratio=2/7

Step-by-step explanation:

let no are x and y

So 5/7 *x=40y/100

x=y*(4/10) / (5/7)

x/y=2/5*5/7

x/y=2/7
