Explanation

Given:

Asad : Sania = 2 : 3

Sania : Fahad = 4 : 3

To find the continued ratio, we need to make Sania's ratio equivalent in both. Let's adjust the ratios:

Asad : Sania = 2 : 3 = 8 : 12 (multiplied both parts by 4)

Sania : Fahad = 4 : 3 = 12 : 9 (multiplied both parts by 3)

Now, combining them:

Asad : Sania : Fahad = 8 : 12 : 9

Explanation

Ratio of boys to girls = 2:3

Number of boys = 12

Let's find the multiplier:

2x = 12

x = 6

Now, find the number of girls:

3x = 3 * 6

= 18

Explanation

Given proportion:

4 : 3 = 8 : p

First, let's find the relationship between 4 and 8:

8 = 2 * 4

Now, apply the same relationship to 3:

p = 2 * 3

p = 6

Explanation

To find the compound ratio, multiply the corresponding parts:

(3 * 8 * 25) : (4 * 15 * 28)

= 600 : 1680

Simplifying the ratio:

= 600 / 1680 = 5/14

= 5 : 14

Explanation

First, convert both to the same unit (grams):

3.5 kg = 3500 grams

280 grams (already in grams)

Ratio = 3500 : 280

Simplifying the ratio:

3500 / 280 = 12.5

280 / 280 = 1

12.5 : 1 = 25 : 2 (after multiplying both parts by 2)
