Question

4. Change a fraction to make a group of like fractions:

$\frac{11}{12},\frac{6}{12},\frac{8}{21},\frac{7}{12},\frac{9}{12}$

Answer 1

Like Fractions: Fractions with the same denominator are known as like fractions.

Converting all the fractions $\frac{11}{12},\frac{6}{12},\frac{8}{21},\frac{7}{12},\frac{9}{12}$into like fractions

L.C.M of 12, 21= 84

$\frac{11}{12}=\frac{11\times 7}{12\times 7}=\frac{77}{84}$

$\frac{6}{12}=\frac{6\times 7}{12\times 7}=\frac{42}{84}$

$\frac{8}{21}=\frac{8\times 4}{21\times 4}=\frac{32}{84}$

$\frac{7}{12}=\frac{7\times 7}{12\times 7}=\frac{49}{84}$

$\frac{9}{12}=\frac{9\times 7}{12\times 7}=\frac{63}{84}$

Thus, $\frac{77}{84},\frac{42}{84},\frac{32}{84},\frac{49}{84},\frac{63}{84}$are the required like fractions.
