We will practice the questions given in the worksheet on multiplication of fractional number by a whole number. We know to multiply a fraction by a whole number, the numerator of the fraction is multiplied by the whole number to get the numerator and the denominator does not change.
I. Multiply the following:
(i) \(\frac{1}{6}\) by 9
(ii) \(\frac{7}{12}\) by 4
(iii) \(\frac{7}{10}\) by 5
(iv) \(\frac{13}{20}\) by 25
(v) \(\frac{17}{19}\) by 38
II. Find the product of the following:
(i) 2 × \(\frac{3}{4}\)
(ii) 3 × \(\frac{2}{3}\)
(iii) 4 × \(\frac{1}{2}\)
(iv) 8 × \(\frac{3}{10}\)
(v) 3 × \(\frac{2}{5}\)
(vi) 5 × \(\frac{1}{4}\)
III. Fill in the blanks:
(i) \(\frac{3}{5}\) × ____ = \(\frac{12}{5}\)
(ii) \(\frac{4}{7}\) × 2 = ____
(iii) \(\frac{9}{11}\) × 2 = \(\frac{.....}{11}\)
IV. Multiply the following:
(i) 4\(\frac{5}{12}\) by 16
(ii) 8\(\frac{3}{15}\) by 30
(iii) 17\(\frac{1}{5}\) by 5
(iv) 4\(\frac{1}{2}\) by 16
(v) 7\(\frac{1}{12}\) by 9
(vi) 6\(\frac{2}{3}\) by 7
