| Question | Answer |
| Proper Fraction | A fraction whose value is less than 1; the numerator is smaller than the denominator. |
| Improper Fraction | A fraction whose value is equal to or greater than 1; the numerator is equal to or greater than the denominator. |
| Mixed Number | The sum of a whole number greater than zero and a proper fraction. |
| Converting Improper Fractions | Divide the numerator by the denominator. If there is a remainder, convert it to a mixed number. |
| Converting Mixed Numbers | Multiply the denominator by the whole number, add the numerator, and place the result over the original denominator. |
| Reducing Fractions | Divide both numerator and denominator by the largest whole number that divides them exactly. |
| Greatest Common Divisor (GCD) | The largest whole number that divides both numerator and denominator exactly. |
| Divisibility Tests | Methods to check if a number is divisible by another (example: divisible by 2 if it ends in 0, 2, 4, 6, 8). |
| Raising Fractions | The process of converting fractions to higher equivalent denominators by multiplying numerator and denominator by the same factor. |
| Least Common Denominator (LCD) | The smallest nonzero whole number into which all denominators will divide evenly. |
| Prime Numbers | Numbers greater than 1 divisible only by 1 and themselves. |
| Adding Like Fractions | Add numerators and keep the same denominator.E |
| Adding Unlike Fractions | Find the LCD, convert fractions to equivalent denominators, then add numerators. |
| Adding Mixed Numbers | Add the fractions first and then the whole numbers; reduce if necessary. |
| Subtracting Like Fractions | Subtract the numerators and keep the same denominator. |
| Subtracting Unlike Fractions | Find the LCD, convert to equivalent fractions, then subtract. |
| Subtracting Mixed Numbers | If borrowing is not needed, subtract normally. If borrowing is needed, convert part of the whole number into a fraction before subtracting. |
| Multiplying Fractions | Multiply numerators and denominators; reduce to lowest terms. |
| Multiplying Mixed Numbers | Convert to improper fractions, multiply, and simplify. |
| Dividing Fractions | Invert the second fraction (reciprocal) and multiply. |
| Dividing Mixed Numbers | Convert to improper fractions, invert the divisor, and multiply. |
| Decimal Place Value | Each digit to the right of the decimal point represents tenths, hundredths, thousandths, etc. |
| Rounding Decimals | The process of approximating a decimal number to the desired place value (e.g., tenths, hundredths, thousandths) |
| Decimal Fraction | A fraction with a denominator that is a power of 10 (10, 100, 1000, etc.), which can easily be written as a decimal. |
| Converting Fractions to Decimals | Divide the numerator by the denominator to obtain the decimal equivalent. |
| Converting Mixed Numbers to Decimals | Change the fractional part of a mixed number into a decimal and add it to the whole number. |
| Converting Decimals to Fractions | Write the decimal digits as the numerator and use the corresponding power of 10 as the denominator. Simplify if possible. |
| Converting Percents to Decimals | Divide the percent value by 100 and remove the percent sign (%). |
| Converting Percents to Fractions | Write the percent as a fraction with denominator 100, then reduce to lowest terms. |
| Adding and Subtracting Decimals | Align decimal points vertically, then add or subtract as with whole numbers. |
| Multiplying Decimals | Multiply as with whole numbers. Then, count the total number of decimal places in both factors and place the decimal point in the product accordingly. |
| Dividing Decimals | Move the decimal point in the divisor to make it a whole number, then move the decimal in the dividend the same number of places. Divide as with whole numbers. |
| Dividing by Powers of 10 | Move the decimal point in the dividend to the left as many places as there are zeros in the power of 10. |
| Multiplying by Powers of 10 | Move the decimal point in the number to the right as many places as there are zeros in the power of 10 |
| Estimating with Decimals | Approximate decimal numbers to a convenient place value in order to quickly estimate sums, differences, products, or quotients. |
