Question

If 400ml of milk is used for 8 pancakes,how much is used for 6

Answer 1

`Use\ the\ proportion:\\\\\begin{array}{ccc}400\ ml&-&8\ pancakes\\\\x\ ml&-&6\ pancakes\end{array}cross\ multiply\\\\\\8x=6*400\ ml\\\\8x=2400\ ml\ \ \ \ \ \ \ \ |divdie\ btoh\ sides\ by\ 6\\\\\boxed{x=300\ ml}\\\\Answer:300\ ml\ of\ milk\ is\ used\ for\ 6\ pancakes.`

Answer 2

So we can do this by finding how much is needed for one pancake first.


`400/8=50`
50ml of milk is needed to make 1 pancake.

From there we can multiply it by 6 to figure out how much we need for 6.

`50*6=300`

Alternatively, you can just divide 400 by 8/6 but some people find that confusing and it's often easier to follow workings if you do the above method.

300ml of milk is needed to make 6 pankakes.
