Answer 1

The correct option is B $2\frac{45}{49}$

We have to multiply the top numbers and the bottom numbers as follows and then simplify it.

$\therefore \frac{13}{7}\times \frac{11}{7}=\frac{13\times 11}{7\times 7}=\frac{143}{49}$

Finally, convert this improper fraction into a mixed fraction by long division method.


$\frac{143}{49}\text{can be written as}\text{Quotient}\frac{\text{Remainder}}{\text{Divisor}}\text{or}2\frac{45}{49}.$
