Question

3/4 is added to x, the result is 9/8 . What is the value of x? Enter your answer in the box as a fraction in simplest form. Please explain your answer, I want to know how you got it.

Answer 1

⓵ Write down your complete equation:

x + ¾ = 9/8

⓶ Solve the equation in order to find the value of “x”:

x + ¾ = 9/8
- ¾ - ¾

x = 9/8 - ¾

There a 3 simple steps to subtract fractions:

⒈ Make sure the bottom numbers (the denominators) are the same.

9/8 - ¾ → They don’t have the same denominator.

You need to multiply the top number and the bottom number of ¾ by 2 :

3 (x2) 6
—- = ——
4 (x2) 8

So now you are left with : 9/8 - 6/8

⒉ Subtract the top numbers (the numerators). Put the answer over the same denominator :

9 - 6 = 3 → ⅜

⒊ Simplify the fraction (if needed) :

⅜ → The fraction is already simplified.

⇨ Your answer is: x = ⅜

There you go! I really hope this helped, if there’s anything just let me know! ☻
