Answer:

Step-by-step explanation:25/4 x p. =0.25

p =25/100 x4/25

p = 0.04

Answer 2

Recall:

To convert fraction into decimal:

⇒ divide the numerator by the denominator

To convert percentage into decimal:

⇒ divide the percentage by 100

Given:

$\dfrac{25}{4} \text{ of a weight } = 0.25 kg$

Convert the fraction to decimal:

$6.25 \text{ of a weight } = 0.25 kg$

Find 1 unit of the weight:

$\text{ the weight } = 0.25 \div 6.25$

$\text{ the weight } = 0.04 \text { kg}$

Find 45% of this weight:

$\text{ the weight } = 0.04 \text { kg}$

$45\% \text{ of the weight } = 45\% \times 0.04 \text { kg}$

$45\% \text{ of the weight } = 0.45 \times 0.04$

$45\% \text{ of the weight } = 0.018 \text { kg}$

Answer: 45% of the weight is 0.018 kg
