Question

If 70% of a number is equal to three fifth of another number, what is the ratio between first number and second number respectively?

Answer 1

Let the first Number be x

Let the first Number be x and the second number be y

According to the Question,

70% of x = 3/5th of y

=> 70/100 x = 1/5 y

=> 7x/10 = y/5

=> 35x/10 = y

=> 35/10 = y/x

=> 7/2 = y/x

=> y/x = 7/2 = 7:2

The ratio of second number with first is 7:2 while ratio of first with the second is 2:7 (ANS)

Note below :-

a:b = a/b and vice versa

a% = a/100

Answer 2

Answer:

6:7

Step-by-step explanation:

hey dude the answer is 6:7 as

70%x =3/5th of y

70/100x=1/5y

7x/10=y/5

35/10=y/x

7:6=y/x

so answer is 6:7
