Answer 1

Step-by-step explanation:

Answer : 1/4 = 0.25%

Explanation :-

Given :

what percent of 7.2kg is 18 gms

Let x% of 7.2kg is 18 g

Changing kilogrammes into grams

1 kg = 1000 g

7.2 = 7.2 x 1000 = 7200 g

x% of 7200 g is 18 g

According to the question

\dfrac{x}{100} \times 7200 = 18

100

x

×7200=18

\dfrac{7200x}{100} = 18

100

7200x

7200x = 1800

X = 1800/7200

x = 1/4 = 0.25%
