We will discuss here about the multiplication of fractional number by a whole number.
14 is multiplied by 4 or 4 β 14 = 4 of 14
So, this figure shows 4 of 14 or 14. (Since, 4 Γ 14 = 14 + 14 + 14 + 14) Therefore, 4 Γ 14 = 41 Γ 14 = 4Γ11Γ4 = 44 = 1 |
Hence we conclude that, to multiply a fraction by a whole number, the numerator of the fraction is multiplied by the whole number. This becomes the numerator of the product. The denominator does not change.
The following rules are given below for the multiplication of a fraction by a whole number:
(a) If the fraction is a mixed fraction, convert it to improper fraction.
(c) Always write the answer as a mixed fraction if it is not a proper fraction/whole number.
