HESI MATH PROBLEMS HOW TO

Whichever number you multiplied the denominator by to get to 10, 100, 1000 needs to also be multiplied to the numerator. If you need to convert a fraction to a decimal, and no calculator is available, a trick is to convert the denominator to 10, 100, 1000, etc. To convert a decimal to a fraction, separate the integer and decimal into their positions, and then find the common denominator. 5 may be thought of as ½.ĭecimals have positions, which are varied by 10. For example, 1.5 has an integer of 1 and a decimal of. A decimal may have an integer in front of it. To multiply or divide mixed fractions, you must convert to improper fractions and then follow the above rules.Ī decimal, like a fraction, represents part of a whole.

To divide simple fractions, flip the divisor and then multiply across.Įxample: 1⁄ 4 ÷ 1⁄ 2 should be rewritten as 1⁄ 4 x 2⁄ 1 = 2⁄ 4 or 1⁄ 2 You simply multiply the numerators and multiply the denominators. To multiply simple fractions, you do not need to have like denominators. If they are unlike, you will need to convert to equivalent like fractions and then add or subtract.Įxample: 2 1⁄ 8 + 3 1⁄ 6 = 17⁄ 8 + 19⁄ 6 = 102⁄ 48 + 152⁄ 48 = 254⁄ 48 which is simplified to 127⁄ 24 or 5 7⁄ 24 Multiplication & Division To add or subtract mixed fractions, first convert them to improper Then if they are like, you may simply add the numerators. To add or subtract unlike fractions, convert the fractions to equivalent fractions of the same denominator, and then simply add or subtract the numerators while keeping the same denominator.Įxample: 1⁄ 2 + 1⁄ 3 = 3⁄ 6 + 2⁄ 6 = 5⁄ 6 To add or subtract like fractions, simply add or subtract the numerators while keeping the same denominator.Įxample: 1⁄ 4 + 1⁄ 4 = 2⁄ 4 which is simplified to 1⁄ 2 by dividing the numerator and denominator by 2. 6⁄ 4 is the improper version of this fraction. It can be rewritten as 6⁄ 4 or 3⁄ 2 or 1.5.

1 2⁄ 4 is a mixed fraction and has a value greater than 1.3 which can be converted to 1⁄ 3 in its fraction form We shall construct a number line to learn some basic aspects of fractions including value, conversion to decimals, equivalence, like, unlike, improper, and mixedĮxample: Place the following numbers on a line from smallest to largest: Fractions can be added, subtracted, multiplied, divided, and converted to decimals.įractions can be equivalent, like, or unlike, and mixed. Like any regular integer, fractions have values that are larger or smaller relative to other numbers. Note that the denominator can never be zero. For example, one half is written as 1⁄2 where 1 is the numerator and 2 is the denominator. Fractions have numerators and denominators. FractionsĪ fraction means a part of a whole.
