Answer: 3/6 + 4/6
Step-by-step explanation:
So the key to this is you can only add fractions with the same denominator. As you can see from this question these denominators (2 and 3) are not the same so we need to change that. We can usually find a common denominator between the numbers but to save time the smallest number that both 2 and 3 go into is 6. so 1/2 becomes 3/6 because 1/2=3/6. And 2/3 becomes 4/6 because 4/6=2/3. Since that's true we can add both 3/6 and 4/6. So when adding fractions remember only add NUMERATORS do not add DENOMINATORS. so 3/6 and 4/6 = 7/6 NOT 7/12.
