True or false?, If I earn 60% more than you,then you must earn 37.5% less than me
neonofarm [45]

Answer:

True

Step-by-step explanation:

We have two salaries:

My salary is A

Your salary is B

If I earn 60% more than you

This means that

A = (1 + 0.6)B = 1.6B

You must earn 37.5% less than me

The ratio between your salary and mine is:

r = \frac{B}{1.6B} = 0.625

Your salary is 62.5% of mine. So you earn 100-62.5 = 37.5%. So this is true.
