Question

how many pieces of length 75 cm can be made from a ribbon roll of length 11m 30cm ? what Will be left over.

Answer 1

total length=11m 30cm
=11×100+30=130cm


$no \: of \: pieces = \frac{total \: length}{length \: of \: one \: piece} \\ = \frac{1130}{75} \\ = 15 \frac{5}{75}$
15 pieces of ribbon would be there. Ribbon used=15×75=1125cm
left piece=1130-1125
=5 cm
