Question

Convert each part of the ratio to percentage:

(a) 3:1

(b) 2:3:5

(c) 1:4

(d) 1:2:5​

Answer 1

Solutions:

(a) 3: 1

First part = 3/4 = (3/4) × 100% = 75%

Second part = 1/4 = (1/4) × 100% = 25%

(b) 2: 3: 5

First part = 2/10 = (2/10) × 100% = 20%

Second part = 3/10 = (3/10) × 100% = 30%

Third part = 5/10 = (5/10) × 100% = 50%

(c) 1: 4

First part = 1/5 = (1/5) × 100% = 20%

Second part = 4/5 = (4/5) × 100% = 80%

(d) 1: 2: 5

First part = 1/8 = (1/8) × 100% = 12.5%

Second part = 2/8 = (2/8) × 100% = 25%

Third part = 5/8 = (5/8) × 100% = 62.5%
