if you still dont understand search up "scientific notation"
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.
