Thus, of 1,1 = 1 of 1, 3 = 1 of 2 or 3 of 1, 2 = 1 of 3 or 4 of 1. You have learned also that a fraction may be regarded as an expression of division in which the numerator is the dividend and the denominator, the divisor. Thus, 1÷2, }=1÷3, } = 2÷3; 1= 16 ÷ 5 =31; 4 = 16 ÷ 4 = 4. = = Change to integers or mixed numbers by dividing the numerator by the denominator: 15. 15, 12, 8, 12, 24, 10, 48, 15, 12, 18, 24. 16. 9, 12, 11, 15, 7, 17, 19, 21, 19, 21, 47.
