Question

Rama has 6 whole 1upon 4 kg of cotton wool for making pillows. If one pillow takes 1 whole 1 upon 4 kg how many pillows can she make?​

Answer 1

Step-by-step explanation:

Total cotton = 6*1/4 kg = 25/4 kg

1 pillow takes 1*1/4 kg cotton = 5/4 kg cotton

Number of pillows that can be formed with 25/4 kg of cotton =>

25/4 × 4/5 = 25/5 = 5 pillows

Answer 2

Answer:

Required numbers of pillow are 5.

Step-by-step explanation:

Given,

Rama has $6 \frac{1}{4} = \frac{6 \times 4 + 1}{4} = \frac{25}{4}$

kg cotton wool.

She wants to make pillow.

Now one pillow takes $1 \frac{1}{4} = \frac{1 \times 4 + 1}{4} = \frac{5}{4}$

kg cotton.

By unitary method we can solve this question.

$\frac{5}{4}$kg cotton is necessary for making 1 pillow.

So, 1 kg cotton is necessary for making $\frac{1}{ \frac{5}{4} } = \frac{4}{5}$

pillow.

$\frac{25}{4}$kg cotton is necessary for making $\frac{4}{5} \times \frac{25}{4} = 5$pillow.

Required numbers of pillow are 5.
