Quizplus · Accepted Answer

The given ratio of 7 to 13 can be written as 7/13. Let x be the unknown term. The ratio of x to 52 can be written as x/52. We can set up the equation:
7/13 = x/52
To solve for x, we can cross-multiply:
7 × 52 = 13 × x
364 = x
Therefore, the value of x is 364, which is choice (D).
