Question

From a rope 75 meter long pieces of equal size are cut,each measuring 7/2 meters.How many pieces are cut off and what fraction is left?

Answer 1

size of rope= 75 m

each have 7/2 m

then no cut piece = 75/7/2

75×2/7

= 21.42 m

Answer 2

Solution :-

Length of rope = 75 m

Length of each piece = 7/2 m

No. of pieces cut off = ?

Fraction left out = ?

.

. . No. of pieces = 75 ÷ 7/2

= 75 × 2/7

= 150/7

= 21 ; 3/7

.

. . No. of pieces = 21

Fraction left out = 3/7 m.
