Answer 1

Answer:

What percent of 7.2kg is 18gm?

Digitize your manufacturing operations. Boost your productivity.

First of all , 7.2 is in kg unit and 18 is in gm unit. So , in order to tell percentage, we need to convert both values in one unit , either in kg or in gm.

So , let’s change 7.2 kg in gram and we find 7200 gm . Now both quantities are in same units so we can find out our answer. So , let’s solve it .

Suppose , 18 gm is x percent of 7200 gm . Then equation is ..

7200 × x/100 = 18

72 × x = 18

x = 18 / 72

x = 1/4 = 0.25

So here is your answer . 18 gm is 0.25% of 7.2 kg .
