Explanation

Total ratio = $2+3=5$

Largest part = 3/5​×500=300​

Explanation

Total ratio parts = 4 + 3 + 2 = 9

1 part = 1800 / 9 = 200 votes

Ms. Frau = 3 parts = 3 * 200 = 600

Explanation

Total parts = 5 + 9 = 14 parts

14 parts = 5,600 tons

1 part = 5,600 / 14 = 400 tons

Larger ship = 9 parts = 9 × 400 = 3,600 tons

Explanation

Let first = A, second = B

2/5 of A = 1/3 of B

A × 2/5 = B × 1/3

A/B = (1/3) / (2/5)

A/B = 1/3 × 5/2 = 5/6

So ratio A : B = 5 : 6

Explanation

Given:

A:B = 3:4

B:C = 8:9

Step 1: Make the value of B equal.

LCM of 4 and 8 = 8

Multiply A:B by 2:

A:B = 6:8

B:C = 8:9

Step 2: Combine the ratios.

A:B:C = 6:8:9

Explanation

For fourth proportion: a : b = c : d

5 : 8 = 10 : x

5/8 = 10/x

5x = 80

x = 16

Explanation

Given:

a : b : c = 3 : 4 : 7

We need to find (a + b + c) : c

Step 1: Add the ratios:

3 + 4 + 7 = 14

Step 2: The value of c = 7

Step 3: Form the ratio:

14: 7

Step 4: Simplify:

14 : 7 = 2 : 1

Explanation

5 → 25, so multiplier = 25 ÷ 5 = 5

Second quantity = 8 × 5 = 40
