Question

Subtract 23/ 30 from 27/27​

Answer 1

• We have to evaluate the above expression by using the given data.

             Given data:- $\frac{27}{27} -\frac{23}{30}.$

             To find:- Value of the given expression.

             Solution:-

• We will take the LCM of the denominators, and make denominators the same.

• We will Convert the given fractions to equivalent fractions with the denominator as the LCM.

• Adding the numerators over the denominators.

        Therefore,

             $\begin{array}{l}\frac{27}{27}-\frac{23}{30} \\\\=\frac{27 \times 10}{27 \times 10}-\frac{23 \times 9}{30 \times 9} \\\\=\frac{270}{270}-\frac{207}{270} \\\\=\frac{270-207}{270} \\\\=\frac{63}{270} \\\\=\frac{63 \div 9}{270 \div 9} \\\\=\frac{7}{30}\end{array}$

     Hence we will get the value is $\frac{7}{30} .$
