Answer:
1/4
Step-by-step explanation:
1/2 is the same as 2/4 as they are equivalent fractions, so we do 2/4-1/4 to get 1/4 which is our answer. Hope this helped!
all angles = 180 degrees total
add the ratios: 2 +4 +9 = 15
180/ 15 = 12
12*2 = 24
12*4 = 48
12*9 = 108
108 + 48 + 24 = 180
the three angles are: 24, 48 and 108
The total cost should be around 19.20
