Final answer:
The expression 2/3(d + 6) is equivalent to (2d + 12)/3.
Step-by-step explanation:
The expression 2/3(d + 6) can be simplified by multiplying the 2/3 with both terms inside the parentheses. This can be done using the distributive property of multiplication. So, 2/3(d + 6) becomes (2/3) * d + (2/3) * 6. Simplifying further, we get (2d/3) + (12/3).
The result is the expression (2d + 12)/3. This is the equivalent form of the given expression.
