Q: If 8/9 = 4x/27, then what is x?
UNANSWERED.
The correct answer is D.
A: The answer is 6.
Cross-multiply to solve for x. 8/9 = 4x/27 8 × 27 = 9 × 4x 216 = 36x 6 = x
A possible shortcut is to simplify the original equation before cross-multiplying: 8/9 = 4x/27 Divide by 4 on both sides 2/9 = x/27 Times by 9 on both sides 2 = x/3 Cross-multiply 6 = x
