Question

Three hens can lay 3 eggs in 3 days.In how many days can 7 hens lay 7 eggs?

Answer 1

Answer: 3 days

Step-by-step explanation: It would take 3 days for seven hens to 7 lay eggs because each hen lays an egg each day.

1 hen/1 egg = 3 days

7 hens/7 days = 14 eggs

7 hens/3 days = 7 eggs

Answer 2

Answer:

3 days

Step-by-step explanation:

Three hens lay 3 eggs in 3 days

We have to find the days in which 7 hens lay 7 eggs

Hen/egg=$\frac{3}{3}$

Hen/egg=1

Using unitary method

1 hen lays 1 egg in 3 days

1 hen lays in 1 day =$\frac{1}{3}$eggs

7 hens lay 7/3 eggs in 1 day

7 hens lay 1 egg=$\frac{3}{7}$days

7 hens lay 7 eggs=$\frac{3}{7}\times 7$

7 hens lay 7 eggs=3 days

Hence, 7 hens lay 7 eggs in 3 days
