< Here's how you do subtraction in fractions!
Make sure you find a least common denominator. Here, it's given to you to be 15. Usually, you can just multiply the two denominators but then it would be quite large at times, so you kind of just have to guess.
How did they go from to
?
Well, they used a least common denominator. 5 was multiplied by 3 to create 15, and 3 was multiplied by 5. But when you multiply the bottoms, you have to multiply the tops of the fraction too (the numerators).
So 4/5x was multiplied by 3. Denominator turned out to be 15, and now the top is 4x3 = 12. So the fraction is 12/15.
1/3x, on the other hand, was multiplied by 5. Denominator was also 15 so they're the same, and top is 1x5 = 5. So the fraction is 5/15.
Now, let's put them together.
When subtracting x, the x just stays there, so if it was 10x-4x, the answer would've been 6x. So now let's subtract!
12-5 = 7, and the denominator stays the same.
The answer is . So the numerator, or answer to your question, would be 7.
