• Sarita bought 87metres of ribbon from sale. She cut them into pieces of 6-m2.each for streamers to decorate the school hall for Christmas. How many pieces did she get? Were there any left?

$\huge\mathfrak\pink{Answer \: ✔}$

= No. of pieces obtained = 14

$\huge\mathbb\purple{Explanation}$

$total \: length \: of \: ribbon \: with \: sarita$

$= 87 \: \frac{1}{2} \: m = \frac{175}{2} \: m$

$now, she \: cut \: the \: ribbon \: into \: pieces \: of \: equal \: lengths$

$now \: length \: of \: each \: pieces = 6 \: \frac{1}{4}$

$m = \frac{25}{4} \: m$

$no. \: of \: pieces \: obtained = \frac{175}{2} \div \frac{25}{4}$

$= \frac{175}{2} \times \frac{4}{25}$

$= 7 \times 2$

$= 14$

$so \: no. \: of \: pieces \: obtained = 14$

$= there \: was \: nothing \: left$
