Adding fractions game
Use this adding fractions game to challenge yourself and to see how fast you can add fractions in 2 minutes. This game should help you master addition of fractions.
You should use any means necessary to get the answer, such as mental math, paper and pencils.
However, I strongly recommend that you do not use a calculator!
How to play:
Same denominators
For instance, if the question is 1/2 + 4/2, do (1 + 4)/2 = 5/2 and enter 5/2
Different denominators, but one denominator is a divisor of the second denominator
For instance, if the question is 3/4 + 4/8, 4 is a divisor of 8 because 4 × 2 = 8
So, do (3 × 2)/(4 × 2) + 2/8 = 6/8 + 4/8 = 10/8 and enter 10/8
If the question is 2/10 + 4/5, 5 is a divisor of 10 because 5 × 2 = 10
So, do 2/10 + (4 × 2)/(5 × 2) = 2/10 + 8/10 = 10/10 and enter 10/10
Different denominators, but no denominator is a divisor of the second denominator
If the question is 3/2 + 1/5, 2 is not a divisor of 5 and 5 is not a divisor of 2.
So, do (3 × 5)/(2 × 5) + (1 × 2)/(5 × 2) = 15/10 + 2/10 = 17/10 and enter 17/10
Remember, do not simplify answers!
Do not forget the "/" (slash)
