and 3 is 10% of 30.Im just wondering because my friend got a different answer, though I forgot what it was.Thanks :)-What percent of 1.5 is 3/20?x/100 times 1.......
okay so I'm in accelerated 7th grade math and we are doing this MathFax thing. Well, one of the questions was "what percentage of 1.5 is 3/20?
I said 10% because 1.5 is 30/20, and 3 is 10% of 30.
I'm just wondering because my friend got a different answer, though I forgot what it was.
Thanks :)

What percent of 1.5 is 3/20?

"What" means a variable
__% means __/100
"Of" means times
"Is" means =

x/100 times 1.5 = 3/20
1.5x/100 = 3/20

Then cross-multiply:
1.5x(20) = 3(100)
30x = 300
x = 300/30
x = 10

Answer: 10%

Yes, you're correct. Whenever you're in doubt, you can always remember to translate the words into math.

Well Raquel...

1.5 can be written as 15/10 or 30/20
3/20 is clearly one-tenth of that, or 10%

I'd say you're right.
