Question

From a rope 40 metres long, pieces of equal size are cut. If the length of one piece is 4 1/4 metre, find the number of such pieces.

Answer 1

40 ÷ 17/4
40 × 4/17
160/17

Answer 2

Total length = 40 m

Length of one piece = 4 1/4

.

Number of equal pieces:

$40 \div 4\dfrac{1}{4}$

$= 40 \div \dfrac{17}{4}$

$= 40 \times \dfrac{4}{17}$

$= \dfrac{160}{17}$

$= 9 \dfrac{7}{17}$

.

Answer: There are 9 such equal pieces
