With percent questions the best way to do it is to use the formula %/100 = is/of. I teach my students this and it works every time.
Your question "What percent of 3.8 is 38?" will fit right into the formula. % is the unknown, so it goes in the formula as x. Of is the number 3.8, and is will be 38. Fill these into the formula, cross multiply and solve for x.
x/100 = 38/3.8 (cross multipy)
3.8x = 3800 (divide both sides by 3.8 to get x alone)
3.8x/3.8 = 3800/3.8
x = 1000%
This makes sence because 3.8 is much smaller than 38, so it makes sence that 38 is 1000% higher than 3.8. Hope this helps. :)

If 3.8 represents 100%, 38 represents ten times that amount, or 1000%. A general method of solving these kinds of problems is to set up a ratio. Three point eight is to a hundred as 38 is to x, and solve for the unknown:
1) 3.8/100 = 38/x
2) 3800 = 3.8x
3) 1000 = x
Question:-
What percent of 3.8 is 38?
Solution:-
Now easy way for solving this is to turn it into an equation form. like this,
Since we want to calculate the percent so lets take 'a' in its place;
a/100 of 38 = 3.8
a/100 x 38 = 3.8
a/100 = 3.8/38
a/100 = 0.1
a = 0.1 x 100
a = 10
Hence the answer is 10%
To check;
According to the answer;
10% of 38 is 3.8
Hence;
10/100 x 38
= 380/100
=38/10
=3.8
Hence Proved....
What percent of 3.8 is 38?
let x be the percent,
x% of 38 = 3.8
x% * 38 = 3.8
x% = 3.8/38
x% = 0.1
x/100 = 0.1
x= 0.1*100
x= 10%
`3.8/100 = 38/x `
3800 = 3.8x
divide by 3.8
1000 = x
3.8=100%
38 is 10 times 3.8 so 100% * 10= %1000
38 is 1000% of 3.8 100%
3.8 is 100% percent
3.8*10=38=100%*10
38= 1000%
What percent of 3.8 is 38?
Of signifies multiplication. The "what percent" can be written as x/100 This problem can be set up as
`(x)/(100) xx 3.8 = 38`
Now we can solve for x:
`x = (38)/(3.8) xx 100`
x = 1000
This means 1000% of 3.8 is 38. We know the percent had to be greater than 1 since 38 is greater than 3.8.
What percent of 3.8 is 38?
cross multiply
x/100 = 38/3.8
3.8x = 3800
divide by 3.8
x = 1000
percentage= worked-out value/ used value * 100%
=38/3.8x100%
= 10 x 100%
= 1000%
