Recall that equivalent fractions can be found by multiplying the numerator and

the denominator by the same number.

So, 9:8 = or .

Thus,we can write 9:8:7 as 9x:8x:7x and use those measures for the triangle sides.        (Since )

                       (Combine like terms)

                                (Divide each side by 24)

Use to determine the measures of each side of the triangle.

9x = 9(6) or 54

8x = 8(6) or 48

7x = 7(6) or 42

The measures of the sides of the triangle are 54, 48, and 42.
