Answer 1

there are three numbers. the first two numbers are 30% and 80% more than the third number respectively. what is the ratio of first two numbers

Answer 2

Answer:

The ratio of the first two numbers is 13:18

Step-by-step explanation:

Let's consider three numbers be x, y, z

They have given that the first number is 30% more than the third number

x = z + 30%z

They have given that the second number is 80% more than the third number

y = z + 80%z

Now consider the ratio of the first two numbers

$\frac{x}{y} = \frac{z + (\frac{30}{100} )z}{z+(\frac{80}{100} )z}$

$\frac{x}{y} = \frac{z(1 + \frac{30}{100} )}{z(1+\frac{80}{100} )}$

$\frac{x}{y} = \frac{130}{180}$

x:y = 13:18

Therefore the ratio of the first two numbers is 13:18
