## Grade 7 Math Worksheets

A proportion is obtained by equating two ratios, which means that two fractions are equal to each other. The quantities which are compared should be of the same type and unit of measurement.

It can be written as *a* : *b* = *c* : *d* or *a* : *b* :: *c* : *d*

The first and the fourth quantities are called the ‘extremes’ while the second and the third quantities are called the “means”.

In a proportion, the product of the extremes is equal to the product of the means.

**Example:**

11 × 9 = 12*v*

99 = 12*v* * v* = 8.25

** Example:** Mary bought one bulb of elephant garlic for $2. How many bulbs can Mofor buy if he has $10?

Let us assume that Mofor can buy *x* bulbs for $10.

Ratio of bulbs = Ratio of costs

1 : *x* = 2 : 10 implies 2*x* = 10

So, *x* = 5
