Here is how you solve this. You use an equation. 18 stays 18. Is means equals. 3/10 stays 3/10. Of means multiply. What number indicates a variable, you can use x.
So:
18=3/10x
Divide by 3/10.
x=60
So, 18 is 3/10 of 60. Hope I helped! :)

The way to solve the problem is to examine what you know. If you know that 18 is 3/10 of a number you know that 18 is 3 times a number so you divide 18 by 3 or 18/3=6. 6 is 1/10 of the number so you need to multiply by 10. 6x10=60

If the number is x,
METHOD - 1
x * 3/10 = 18
Cross Multiply
x = 180/3
x = 60
So, 18 is three tenths of 60
METHOD - 2
18/x = 3/10
Cross multiply
x = 60
So, 18 is three tenths of 60

If 18 is 3/10 of the number then the number must be 18/(3/10)
i.e. 180/3 = 60.
18 is 3/10 of 60.

If you want to know how to answer these questions, remember 2 things. Is means equals and of means multiply. So you get
18=3/10*x
Now solve to get
x=18*10/3=60

translation tip:
N is (M) of what number means
N = M * number
so number = N / M <======== simple rule
18 is (three tenths) of (what number) means
18 is (3/10) of (what number), or
18 = (3/10) * number
number = 18 / (3/10) = (18*10)/3 = 60
