Answer:
First what you want to do is find what fraction is equal to 1/4 and has a denominator of 20.
The way you can find this is by taking 1/4 and seeing how many times the denominator or 4 will go into 20.
4 * 5 = 20
Since 4 times 5 is 20, we will multiply 5 to the numerator of the fraction to.
1 * 5 = 5
So 5/20 is = to 1/4
x = 5
Now the question says, " x less thsn the denominator" so we just need to find how much less is 5 compared to 20.
20 - 5 = 15
The numerator has a value, "15 less than the denominator."
