We will practice the questions given in the worksheet on multiplicative inverse of a fractional number.
We know, to get the reciprocal of a given fraction, we interchange the numerator and the denominator and if we multiply the reciprocals, the product is one.
I. Find the reciprocal of the following:
(i) \(\frac{2}{3}\)
(ii) \(\frac{5}{12}\)
(iii) \(\frac{1}{12}\)
(iv) \(\frac{1}{18}\)
(v) 1
(vi) 8
(vii) 1\(\frac{2}{3}\)
(viii) 33\(\frac{1}{3}\)
(ix) 17
II. Fill in the blanks:
(i) \(\frac{1}{27}\) × ____ = 1
(ii) \(\frac{42}{1}\) × \(\frac{1}{.......}\) = 1
(iii) Reciprocal of 9/4 is ____
(iv) Multiplicative inverse of 28 is ____
(v) Multiplicative inverse of 31 is ____
(vi) The reciprocal of ____ is equal to itself.
(vii) The reciprocal of whole number will always be a ________ fraction.
(viii) The multiplicative inverse of mixed number will always be a ________ fraction.
III. State whether these are reciprocals of each other:
(i) \(\frac{1}{2}\), 2
(ii) \(\frac{3}{2}\), \(\frac{3}{2}\)
(iii) \(\frac{5}{9}\), \(\frac{9}{5}\)
(iv) \(\frac{5}{11}\), \(\frac{4}{11}\)
(v) 5\(\frac{1}{3}\), \(\frac{16}{3}\)
(vi) \(\frac{2}{3}\), 1\(\frac{1}{2}\)
