Now, they each have two pieces of the pie, which is in four pieces. Two equivalent fractions will be the same when completely reduced written in simplest form. When one or both of the fractions contain large numbers, it may not be in your best interest to try to reduce or simplify them, although you certainly could do this.
A more efficient way is to cross multiply. For example, say you are asked to compare the following two fractions:. Since the cross products are the same, the fractions are equivalent. If the product on the left were greater than the product on the right, the fraction on the left would be the larger of the two. Similarly, had the product on the right been larger, the fraction on the right would be the larger of the two. Reducing and simplifying fractions requires you to be able to identify the common factors between the numerator and the denominator.
The divisibility rules come in handy here! You are looking for factors that can divide both the numerator and the denominator. One way to do this is to write out the prime factorization of both. Another is by inspection.
Alternatively, you can use inspection to look for common factors. Since both and end in zeros, they are both divisible by Improper fractions typically make an appearance on the SAT. They are simply fractions that represent a whole number. When you see an improper fraction on the test, you will typically see answer choices with mixed numbers, meaning numbers that represent an improper fraction as a whole number and a fractional component. Three 3 divides into 7 twice with a remainder of 1.
This happens most often when multiplying or dividing with fractions. To do this, simply multiply the whole number by the denominator, add the result to the numerator, and divide the sum by the denominator. In this section, we will use diagrams to divide fractions and mixed numbers a.
