Make a ratio and solve for x:

48/x = 30/100

remember % means 'per 100'

% means 1 / 100

48 % of 30 = ?

48 % = 48 / 100

48 % of 30 = [48 / 100] * 30

= [48*30] / 100

= 1440 / 100
]
= 14.40

thus 48% of 30 = 14.40

So D

"48 is 30% of <b>what number</b>?"

48/x = 30/100

48/x = 3/10

3x = 480

x = what?
Answered by Johnny McKarron is cool
x=160 because you divide by 3 on both sides
Answered by Vin Mwale
30%=48 so 100% =more. Therefore it will be 100%/30%*48. So the answer is 160
