Question

Youssef paid AED 8 for 12 eggs.
Determine the cost of 3 eggs.

Answer 1

Solving:

To solve this problem, you must first know how much 1 egg costs, for this we have to divide:

$\begin{matrix}\space\space\space\space\space\space\emptyspace \sf 1,5\space\space\space\space\space\space\space\space\space\space\space\space\\ \sf 8\overline{|\smallspace \sf 12}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}\\\underline{\sf 8}\\\sf 40\\\underline{\sf 40}\\(0)$

• Now we know an egg costs $1.5, so:

$\sf 1,\:5\:+1,\:5+1,\:5=\boxed{\sf 4,5}\ll Eggs$

Okay?!

Answer 2

Answer:

  AED 2 for 3 eggs

Step-by-step explanation:

Price (p) is proportional to the number of eggs:

  p/3 = 8/12

  p = 3(8/12) = 8(3/12) = 8/4 = 2

The cost of 1/4 as many eggs will be 1/4 as much: AED 2 for 3 eggs.
