Though a fraction represents a single value, some mathematical operations treat its two numbers separately. A fraction is composed of two whole numbers, one as the numerator on top and the other as a denominator on the bottom. A proper fraction possesses a denominator that is greater than its numerator. Exponents, also defined as powers, affect a number by multiplying the number to itself an indicated number of times. Squaring a number is a term for raising it to its second power. In squaring a fraction, both its numerator and denominator are raised.

Multiply the numerator of the fraction by itself. In the example of 7/10, 7 multiplied by 7 equals 49.

Multiply the denominator of the fraction by itself. In this example, 10 multiplied by 10 equals 100.

Place the square of the numerator over the square of the denominator. Concluding this example, placing 49 over 100 equals 49/100. The square of 7/10 is 49/100.
