answer: 1/3 + 1/6 = 2/6 + 1/6 = 3/6 or 1/2
Step-by-step explanation:
whatever you do to the denominator you have to do to the numerator so that the final value is still equal to the initial value.
To get 1/3 to 1/6, you have to multiple the denominator by 2, which means you also need to multiply the numerator by 2.
