3/4 + 1/4 =

1 OR 4/4

If 1 is the answer, you get double points

200

2/6 + 1/3 =

Convert 1/3 to 2/6 by multiplying both sides by 2

After, you would get 4/6

300

4/5 + 3/10

Then, you would get 9/10

400

2 and 1/5 + 2 and 3/5

4 and 4/5

500

6/8 + 2/4

First, convert 2/4 to 4/8 by multiplying both sides by 2

After, your answer would be 10/8 or 1 and 2/8

100

3/4 - 1/4 =

2/4

200

5/10 - 2/10 =

3/10

300

1 and 3/4 - 1 and 2/4 =

1/4

400

2 and 1/4 - 1 and 1/4 =

Only 1!

1 and 0/4 is NOT acceptable

500

DOUBLE POINTS

14/8

Simplify then convert to mixed number

1. Divide both the top and bottom numbers by 2
   • 14 ÷ 2 = 7
   • 8 ÷ 2 = 4
     
     
2. This gives you the simplified fraction of 7/4
3. Convert to mixed - 1 and 3/4
