Answer:
a) 40
b) 80
c) 77
d) 48
Step-by-step explanation:
To find the missing numerator, multiply the equation by the denominator of the fraction with the missing numerator.
a) (10/15)(60) = (x/60)(60)
40 = x
__
b) (x/180)(180) = (4/9)(180)
x = 80
__
c) (7/11)(121) = (x/121)(121)
77 = x
__
d) (x/144)(144) = (2/6)(144)
x = 48
Just cross multiply basically divide
34 x 0.07375= 2.5075
2.5075 + 34 =36.51
or
34×1.07375=36.51
38+39+40 = 117.
So the first of the three numbers is 38.
