Adding Fractions
Add the following fractions:
1/3 + 2/3
3/3 or 1
5/6 - 1/2 =
2/6 = 1/3
1/2 x 1/3 =
1/6
1/3 : 1/6 =
6/3 = 2
Simplify this fraction
36/18
Add these fractions. Are they like or unlike fractions? why?
2/5 + 1/5 =
3/5
They are like fractions.
Denominators are the same number.
2/3 - 1/7 =
11/21
2/5 x 2/7 =
4/35
2/5 : 1/9 =
18/5
Fractions and decimal numbers are related because...
They both represents parts of a whole
Add these fractions. Are they like or unlike fractions? Why?
1/2 + 1/3 =
They are unlike fractions.
Denominators are not the same.
Answer:
5/6
1 - 1/7 =
6/7
3/8 x 2/9 =
6/72 = 1/12
5/7 : 1/4 =

How do you find the least common denominator in these two fractions?
1/9 + 1/3 =
One denominator is a multiple of the other, so you only need to change the second fraction (multiply 3x3 and 1x3). You gen an equivalent fraction that you can then add.
Answer:
4/9
5/7 - 1/7 =
4/7
Multiply these fractions and then convert the result in a decimal number:
2/50 x 1/2 =
0.02
4 : 1/3 =
12
A reciprocal is
when you flip numerator and denominator
