I learned how to add and subtract fractions. Its really easier and thats why I chose it. but all you got to do is these 3 easy steps.
4/8 + 7/4=
what you need to do is find common denominators. So 4 and 8 4 goes into 8 2 times so
4/8 (*1) + 7/4 (*2)=
4/8+ 14/8=
18/8 = 2 1/4
For the recipe that paige has she needs to make cookies she has to have 3 1/2 cups of milk and after she mixes it she needs to add a additional 2/3 cup of milk. How many cups of milk does she need for the cookies?
first we need to find out what we need to do. It looks like we need to add. Lets do this..
3 1/2 + 2/3=
we need to find the common denominators 3*2 = 6 and 2*3= 6 so the common denominator is 6 so times 2/3 by 2 and 3 1/2 by 3 but be careful make sure the 3 1/2 turns into a fraction before you times it.
7/2 (*3) + 2/3 (*2) =
21/6 + 4/6=
25/6=
Paige needs 4 1/6 cups of milk .
