The number is 7.

10: 3n = 2(n + 5); 3n = 2n + 10; (subtract 2n from each side) n = 10.

The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.

It is the sum of the whole number part and the fractional part. eg 5 2/3 = 5 + 2/3
