The difference of two numbers is equal to 0.6. Their quotient is also 0.6. What are the numbers?

Murrr4er [49]

Solution:

we are given that

The difference of two numbers is equal to 0.6.

Let the numbers be x and y so we can write

$x-y=0.6......(i)$

Their quotient is also 0.6.

so we can write

$\frac{x}{y} =0.6.....(ii)$

Now solve these two equations together we get

$0.6y-y=0.6......(i)$

$-0.4y=0.6$

$y=-3/2=-1.5$

$x =0.6+y$

$x =0.6-1.5=-0.9$

Hence the numbers are -1.5 and -0.9
