Adding Fractions

100

Make sure your answer is in SIMPLEST form! 3/8 + 3/8=

6/8=3/4

(Since the denominators are the same, add the numerators and reduce)

(Top and bottom are divisible by 2 so that's why it reduces to 3/4)

200

Make sure your answer is in SIMPLEST form! 3/9 + 2/9

5/9

(Since the denominators are the same, add the numerators - can't be reduced because the top and bottom aren't divisible by the same number)

300

Make sure your answer is in SIMPLEST form! 5/12 + 4/12

9/12 = 3/4

Numerator and Denominator are both divisible by 3 so it reduces to 3/4

400

Make sure your answer is in SIMPLEST form! 2/12 + 8/12

10/12 = 5/6

(Denominator is the same so add the numerators and reduce)

(Top and bottom are both divisible to by and reduce to 5/6)

500

5/16 + 1/16 + 2/16

8/16 = 1/2

Add all of the numerators because the denominators are the same then reduce!
