Subtracting fractions is really easy tbh
All you have to do is get the denominators to be the same and afterwards you just subtrat the numerators.
Multiplying fractions is obviously easier all you do is multiply the numerators across and then the denominators.
however, when dividing fractions always remember ((keep, change, flip)) its helps
The first fractions stays the same, the division sign turns into a multiplication sign and then you turn the last fraction into its reciprocal and just multiply across.
To find the answer to your equation you must solve for x. In other words just divide 2/4 and 1/2 which wold give you the value to ex.
HOPE THIS HELPED XX
