Find the missing numerators in each of the following problems. a. 10⁄15 = ⁄60 b. ⁄108 = 4⁄9 c. 7⁄11 = ⁄121 d. ⁄144 = 2⁄6

We will find the numerator step by step for each expression:
 For 10/15 = x / 60
 x = (10/15) * (60)
 x = 40

 For  x / 108 = 4/9
 x = (4/9) * (108)
 x = 48

 For  7/11 = x / 121
 x = (7/11) * (121)
 x = 77

 For  x / 144 = 2/6
 x = (2/6) * (144)
 x = 48

X=3 and y=4 is the answer
