Final answer:
The situation that can be represented by 1/2 + 3/4 = 3/8 is subtracting fractions.
Step-by-step explanation:
The situation that can be represented by 1/2 + 3/4 equal 3/8 is d) Subtracting fractions.
When subtracting fractions, you need to have a common denominator. In this case, the common denominator is 8. So we need to convert 1/2 to an equivalent fraction with a denominator of 8. Multiplying the denominator (2) by 4 gives us 8, so we multiply the numerator (1) by 4 as well, resulting in 4/8.
Now we can subtract the fractions: 4/8 - 3/8 = 1/8. Therefore, the situation can be represented by 1/2 - 3/4 = 3/8.
