What are ratio and proportion?

A comparison of two quantities by division is called a ratio and the equality of two ratios is called proportion. A ratio can be written in different forms like x : y or x/y and is commonly read as, x is to y.

On the other hand, proportion is an equation that says that two ratios are equivalent. A proportion is written as x : y : : z : w, and is read as x is to y as z is to w. Here, x/y = z/w where w & y are not equal to 0.

Let the quantity of butter required for new recipe be x.

Now, 8:1.5::28:x

Product of extremes=8×x=8x

Product of means=28×1.5=42

Product of extremes=Product of means

⇒8x=42

⇒x=5.25

Therefore, to serve 28 people Joaquin requires 5.25 cups of butter.
