Step-by-step explanation:
Fractions can be thought of as another way of seeing division. If you have one whole pizza and two people want to share it equally, they will divide it into two halves:
The bottom number of a fraction is the denominator. It tells how many parts a whole has been divided into. In this case our pizza is divided into two parts.
Multiplying fractions is fairly simple. You may want to put each fraction in its lowest terms to start. Then multiply the numerators to get a numerator and multiply the denominators to get a new denominator. And reduce or simplify the fraction to put it in its lowest terms. If you are multiplying a fraction by an integer, put the integer over one to make a fraction of it.
Examples:
Five times 4/5: Put the five over one, then multiply 5 x 4 to get 20 and 1 x 5 to get 5. Twenty can be divided evenly by 5 to give us an answer of 4.
Reciprocals of Fractions
The product of a number and its reciprocal equals 1.
Signs and Fractions
If either the denominator or numerator is negative, the fraction is considered a negative fraction. If both the denominator and the numerator are negative, the fraction is considered to be a positive fraction.
Adding two fractions of the same sign (either positive or negative) gives an answer with the same sign. You may need to give the fractions common denominators first.
