Remember: When adding or subtracting fractions, we must make equivalent fractions with common denominators if the denominators do not match. 1) 6 11 15 + 6 4 2 5 3 2 1 15 4 6 3 8 6 15 3 Remember: When adding or subtracting fractions, we must make equivalent fractions with common denominators if the denominators do not match. 6 2) 11 15 - 6 8 2 3 5 1 3 15 2 6 3 8 6 15 4 Remember: When subtracting we may need to rename the whole number and add one to the fraction and change the mixed fraction to improper. 3) 5 11 15 - 6 8 2 3 5 1 1 15 2 5 13 15 6 15 4 Remember: When adding mixed numbers do not leave the fractional part improper. 4) 7 7 15 + 6 4 2 3 5 2 4 22 15 5 13 15 7 15 4 5) 7 7 15 + 6 4 2 3 6 2 5 9 6 6 3 2 7 2 1 6) 6 1 6 - 5 8 2 3 6 1 1 6 5 5 1 6 6 3 2 7) 6 1 6 - 5 8 2 3 2 2 1 6 5 5 1 6 6 3 2 8) 7 5 8 + 6 4 2 3 5 2 3 19 15 6 5 8 7 15 4 Remember: When multiplying and dividing fractions change mixed to improper first. 9) 8 1 35 8 4 5 1 12 35 x 9 2 7 1 8 15 4 Remember: We can't divide fractions so we multiply by the reciprocal instead...want to get it right flip it on the right. 10) 2 1 5 2 4 5 1 ÷ 2 2 1 10 10 1 2 15 1 11) 6 4 5 3 1 7 4 ÷ 1 57 9 6 1 5 2 1 12 12) 1 2 25 8 12 35 ÷ 10 2 2 1 8 15 4 15 ¾ 13) 12 4 5 1 20 3 x 15 3 4 3 12 20 19 4 14) 4 2 5 1 10 7 x 5½ 2 2 1 5 10 7 7½ 15) 2 7 1 49 30 x 6½ 3 2 1 6 14 1 1 16) 1 5 2 2 4 5 4 15 ÷ 6 2 3 1 8 15 2 5 1 |
