Can the answer X
Then the problem is: 0.7 = 19% of X, find X.
X = 0.7 / 19% = 0.7 / 0.19
I'm sure you can do the arithmetic.

answer:3.68.(if 0.7 is 19% of a number, then x is 100%of that number; cross multiply the integers and then make x the subject ;(transposition)

ok.... you set up your proportions, first. you have .7/x = 19/100.
then, you cross-multiply.
x times 19 = 19x.
.7 times 100 = 70
so then you have 19x = 70
divide by 19 on both sides
x = 19/70 OR 3.6842 (round as needed)

Part Percent
_______ =__________
Whole 100
Put in 0.7 /X=19/100
Cross multiply, and solve for X. X is the "whole" in the equation.

You divide .19 by .7 and you get
3.6842105 and it goes on forever or you can just round it to 3.7

First you take 100 divided by 19, you get 5.26 (roughly). Then you multiply that by .7 and you get roughly about 3.7.
That was a good question!

19/100 x X = 0.7
19X = 70
X = 70/19
The number = 3.684210526

Let x be the number and 0.19 x = 0.7 (19% is same as 0.19)
or x = 0.7/0.19 = 3.684...
