Question

− 1/ 3 − (− 4/ 9 ) A) − 1/ 2 B) − 7 /9 C) 1/ 9 D) 7/ 9

Answer 1

1) Simplify brackets

-1/3+4/9

2) Find the Least Common Denominator (LCD) of 1/3, 4/9

LCD = 9

3) Make the denominators the same as the LCD

-((1 times 3)/(3 times 3)) + 4/9

4) Simplify. Denominators are now the same

-3/9 +4/9

5) Join the denominators

(-3+4)/9

6) Simplify

1/9

Your answer is C) 1/9
