Question

. Convert each part of the ratio to percentage:
(a) 1:2:4 (b) 2:3:5 (c) 12:32​

Answer 1

Answer:

a)- % of first part = 1/1+2+4 ×100=14.28%

% of second part = 2/1+2+4 ×100 = 28.57 %

% of third part = 3/1+2+4 = 42.85 %

b)- % of first part = 1/2+3+5 ×100 = 10%

% of second part = 2/2+3+5 ×100 = 20%

% of third part = 3/2+3+5 ×100 = 30%

c)- % of first part = 1/12+32 ×100 = 1.84%

% of second part = 2/12+32 × 100 = 3.70%

Answer 2

Step-by-step explanation:

(a) sum of the ratio=1+2+4=7

1st ratio=1/7 × 100%=14.28%

2nd ratio=2/7×100%=28.57%

3rd ratio=4/7×100%=57%

(b) sum of the ratio=2+3+5=10

1st ratio=2/10×100%=20%

2nd ratio=3/10×100%=30%

3rd ratio=5/10×100%=50%

(c) sum of the ratio=12+32=44

1st ratio=12/44×100%=27.27%

2nd ratio=32/44×100%=72%
