Which number would replace X to make these fractions equivalent? 6/X = 9/13

Answer 1

To solve for X, you need to set up a proportion using the given information.

The proportion can be set up as:

6/X = 9/13

To solve for X, you can cross-multiply:

6 * 13 = 9 * X

78 = 9X

To isolate X, divide both sides of the equation by 9:

78/9 = X

X = 8.67

Therefore, the number that would replace X to make the fractions equivalent is 8.67.
