Question

if mary reads 1/11 of a book on monday and 2/7 on tuesday, what part of the book is left to be read?

Answer 1

➤ Answer :-

Part of book left to read $=$

$\dashrightarrow \tt1 - \frac{1}{11} + \frac{2}{7}$

$\dashrightarrow \tt \frac{1}{1} - \bigg( \frac{1}{11} + \frac{2}{7} \bigg)$

LCM of 1,11 and 7 is 77.

$\dashrightarrow \tt \frac{1 \times 77}{1 \times 77} - \bigg( \frac{1 \times 7}{11 \times 7} + \frac{2 \times 11}{7 \times 11} \bigg)$

$\dashrightarrow \tt \frac{77}{77} - \bigg( \frac{7}{77} + \frac{22}{77} \bigg)$

$\dashrightarrow \tt \frac{77 - (7 + 22)}{77}$

$\dashrightarrow \tt \frac{77 - 29}{77}$

$\dashrightarrow \tt \frac{48}{77}$

$\Huge\therefore$The answer is $\tt\frac{48}{77}$
