Work out and simplify where possible

a} 3/10 + 1/3

b} 3/4 - 2/11

A} 19/30

B} 25/44

Step-by-step explanation:

A} Multiply the numerator and the denominator (3/10) by 3. You would get 9/30. Then multiply the numerator and denominator (1/3) by 10. You would get 10/30. Then add 9/30 + 10/30. It equals 19/30, and it can't be simplified.

B} Multiply the numerator and denominator (3/4) by 11. Then multiply the numerator and denominator (2/11) by 4. You would get 33/44 - 8/44. It equals 25/44. It can't be simplified.
