Answer:
a. 1:9 = [1/(1+9) × 100]%= [1/10 × 100]% = 10%
b. 12:13 = [12/(12+13) × 100]% = [12/25 × 100]% = 48%
c. 3:5:2 = [3/(3+5+2) × 100]% = [3/10 × 100]% = 30%
d. 3:7 = [3/(3+7) × 100]% = [3/10 × 100]% = 30%

Step-by-step explanation:
a. 1:9 = 1/(1+9)×100= 1/10×100 =
10% , 9/(1+9)×100= 9/10×100=90%
b. 12:13 = 12/(12+13)×100 = 12/25×100 = 48% , 13/(12+13)×100= 13/25×100=52%
c. 3:5:2 = 3/(3+5+2)×100= 3/10×
100 = 30% , 5/(3+5+2)×100= 5/10×100= 50% , 2/(3+5+2)×100= 2/10×100=20%
d. 3:7 = 3/(3+7)×100= 3/10×100 =
30% , 7/(3+7)×100 = 7/10×100=70%
hope it helps you!
