Question

7) Three workers built half of a wall. The other half was built by 6 others. (i) What fraction of the wall did each in the first group build? (ii) What fraction of wall did each in the next group built?
Ans= (i) 3 workers built =1/2
1 worker built=1/2/3
=1/2×3
=1/6
each worker built =1/6
(ii)6 workers built =1/2wall
Therefore,1 worker built=1/2/6
=1/2×6
=1/12​

Answer 1

Ans= (i) 3 workers built =1/2

1 worker built=1/2/3

=1/2×3

=1/6

each worker built =1/6

(ii)6 workers built =1/2wall

Therefore,1 worker built=1/2/6

=1/2×6

=1/12​

Answer 2

Answer:

(i) 3 workers built =1/2

1 worker built=1/2/3

=1/2×3

=1/6

each worker built =1/6

(ii)6 workers built =1/2wall

Therefore,1 worker built=1/2/6

=1/2×6

=1/12
