Question

The sum of two rational numbers is 4. If one of the numbers is 2/3, then what is the other number

Answer 1

10/3

Explanation:

Let x be the value of the second rational number. The first rational number is 2/3, and we are told that the sum of these numbers is 4:

x + 2/3 = 4

Therefore:

x + 2/3 = 4

x = 4 - 2/3

x = 12/3 - 2/3

x = (10/3)
