Rewrite the fractions with the same LCD.
pantera1 [17]

4 = 2*2

6 = 2*3

9 = 3*3

LCD = 2 * 3* 2 * 3 = 36

so the fractions are 3/4 * 9/9 = 27/36

5/6 = 30/36 and 5/9 = 20/36

kobusy [5.1K]
7/6x=140

since variable x is multiplied by 7/6, find x by multiplying by the inverse of 7/6 which is 6/7.

7/6x × 6/7 = 140 × 6/7
x= 120
