Subtracting Fractions.<br><br> Fill in the blanks, and the tenth one is 4 2/3 + 7 7/10=
GrogVix [38]
Hello! Although I can't give you the answers automatically. I'll just show you some steps on how to subtract & if you're still not figuring it out just message me! :)

Step 1: You have to make sure both denominators are both exactly the same or you won't get the answer correctly.

Step 2: Then subtract the numerators

Step 3: Simplify if needed.

Ex; If I have 1/2 of the pizza and my friend has 1/6 of the pizza. What will be my result if I subtract the fractions?

We'll have to take 1/2 and 1/6. You'll have to find what makes those numbers, what I mean is by multiplying both numerators and denominators.

\frac{1}{2}  -  \frac{1}{6}  =
You multiply by 3.
2 x 3 = 6

Then you'll change the denominator into 1/2 = 1/6

Result:
\frac{3}{6}  -    \frac{1}{6}  =
Then you just subtract.
3 - 1 = 2

Hint: Denominator never changes when you have your final result. So it's 2/6. It needs to be simplified.

\frac{2}{6}  \div  \frac{1}{3}
We divide by 2.

I hope this example helped you understand how to subtract fractions & if you don't know how to add mixed fractions you can always do around the world or other examples your teacher can provide! :)
