What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance around it, calculated as $$P = 2 \times (length + width)$$ .

How do you find the perimeter using fractions?

When using fractions to find the perimeter, ensure all measurements are in the same units. For example, if the length is $$\frac{1}{2}$$ yard and the width is $$\frac{1}{3}$$ yard, the perimeter is $$P = 2 \times igg(\frac{1}{2} + \frac{1}{3}igg) = 2 \times \frac{5}{6} = \frac{5}{3} \text{ yards}$$ .

What is a reciprocal?

A reciprocal of a number is 1 divided by that number. For example, the reciprocal of $$\frac{2}{3}$$ is $$\frac{3}{2}$$ .

How do you simplify a fraction?

What is the relationship between multiplication and division of fractions?

Multiplication of fractions increases the value, while division of fractions decreases the value. For example, multiplying $$\frac{1}{2}$$ by $$\frac{1}{2}$$ gives $$\frac{1}{4}$$ , while dividing $$\frac{1}{2}$$ by $$\frac{1}{2}$$ gives 1.
