Given:
18 points on her quiz
24 points is equivalent to 100%

18 is to 24 or 18/24
x is to 100% or x/100%

18/24 = x/100%

18 * 100% = 24x
1800% = 24x
1800%/24 = x
75% = x

18/24 = 75%/100%
18 * 100% = 24 * 75%
1800% = 1800%

Answer:

Step-by-step explanation:

Let the number of cockles be c and that of winkles be w.

From the first relation,

w = 2c ..........(I)

From the second relation, 6 winkles are accidentally split.

This in equation form means the following:

c/w- 6 = 3/5

By cross multiplication,

5c = 3(w - 6)...........(ii)

We know w = 2c , let’s substitute this into the second equation.

5c = 3(2c - 6)

5c = 6c - 18

Collecting like times, c = 18

And w = 2c = 2(18) = 36

Hence, there were initially 18 cockles and 36 winkles
