A number is 2/3 if another number. the sum of the numbers is 50. find the numbers
slava [35]

A number is 2/3 of another number.  Both added together equals 50.

One of these numbers consists of three parts, and the other consists of two of those three parts.  So, there are 5 equal parts in total.

Thus we need to divide 50 by 5.  50 divided by 5 equals <u>10</u>.

The first number, which has three parts, is 30.  The second number, which as two parts, is 20.

I hope this makes sense to you.  :D  Good luck in all your studies!

P = (6.50f) - 100

All you have to do is plug in 25 for f in the equation and solve for P.

P = (6.50*25) - 100

P = 162.5 - 100

P = 62.5
