Water and orange squash is mixed in the ratio 5 : 2Find how much water is needed to dilute 160 cl of orange squash.

To find out how much water is needed to dilute 160 cl of orange squash, we need to use the given ratio of water to orange squash, which is 5:2.

Step 1: Understand the ratio The ratio 5:2 means that for every 5 parts of water, there are 2 parts of orange squash.

Step 2: Determine the total number of parts The total number of parts in the mixture is 5 (water) + 2 (orange squash) = 7 parts.

Step 3: Calculate the amount of one part Since the total mixture is divided into 7 parts, we need to find out how much one part is when the orange squash is 160 cl.

One part = 160 cl (orange squash) / 2 (parts of orange squash) = 80 cl per part.

Step 4: Calculate the amount of water needed Since the ratio specifies 5 parts of water, we multiply the amount of one part by 5.

Amount of water needed = 80 cl (one part) * 5 (parts of water) = 400 cl.

Therefore, 400 cl of water is needed to dilute 160 cl of orange squash.
