# Convert each part of the ratio to percentage: (a) 3 : 1 (b) 2: 3: 5 (c) 1:4 (d) 1: 2: 5

(a) 3: 1

To find total parts will first add the given ratio

On adding the given ratio = 3 + 1 = 4

= 3/4 = (3/4) × 100 %

= 3 × 25%

= 75%

Now let us solve 2nd part

= 1/4 = (1/4) × 100%

= 1 × 25

= 25%

(b) 2: 3: 5

To find total parts will first add the given ratio

On adding the given ratio = 2 + 3 + 5 = 10

= 2/10 = (2/10) × 100 %

= 2 × 10%

= 20%

Now let us solve 2nd part

= 3/10 = (3/10) × 100%

= 3 × 10

= 30%

Then the 3rd part

= 5/10 = (5/10) × 100%

= 5 × 10

= 50%

(c) 1:4

To find total parts will first add the given ratio

On adding the given ratio = 1 + 4 = 5

= (1/5) = (1/5) × 100 %

= 1 × 20%

= 20%

Now let us solve 2nd part

= (4/5) = (4/5) × 100%

= 4 × 20

= 80%

(d) 1: 2: 5

To find total parts will first add the given ratio

On adding the given ratio = 1 + 2 + 5 = 8

= 1/8 = (1/8) × 100 %

= (100/8) %

= 12.5%

Now let us solve 2nd part

= 2/8 = (2/8) × 100%

= (200/8)

= 25%

Now the 3rd part

= 5/8 = (5/8) × 100%

= (500/8)

= 62.5%
