Question

If 15% of a number is equal to 90% of another number, what is the ratio of first to
second number is​

Answer 1

Answer:

6:1

Step-by-step explanation:

Let the furst number be x and second number be y.

$\frac{15}{100} \times x = \frac{90}{100} \times y \\ 15 \times x = 90 \times y \\ \frac{x}{y} = \frac{90}{15} \\ \frac{x}{y} = \frac{6}{1}$

Answer 2

Step-by-step explanation:

40/100 is 40%. This comes out to be 2/5.

Now, 2/5 X (say first number) is equal to 2/3 Y (i.e. 2nd number).

These are equated. It means 2/5 X = 2/3 Y

Now we want to get X/ Y. Hence, 2/5 x reverse of 2/3, i.e. 3/2

2/5 x 3/2 comes out to be 3/5 or 60% if we want to put it in terms of percentage.
