Answer 1

a)
100% - 200
76% - x

x = 76% * 200 / 100%
x = 15200 / 100
x = 152
==================================
b)
90 - 100%
x - 67%

x = 90 * 67% / 100% 
x = 6030 / 100
x = 60,3
==================================
c)
780 - 100%
x - 13%

x = 780 * 13% / 100%
x = 10140 / 100
x = 101,4
==================================
d) 
80 - 100%
24 - x

x = 24 * 100% / 80
x = 2400 / 80
x = 30%
