TermDefinitionExample Mixed NumberA number consisting of a whole number and a proper fraction.$3 \frac{1}{2}$ (three and one-half) Improper FractionA fraction where the numerator is greater than or equal to the denominator.$\frac{7}{2}$ (seven-halves), which is equivalent to $3 \frac{1}{2}$ Inverse OperationsOperations that undo each other. Addition is the inverse of subtraction, and subtraction is the inverse of addition.To solve $x + 5 = 8$, you use the inverse operation of subtraction: $x = 8 - 5$. To solve $x - 3 = 7$, you use the inverse operation of addition: $x = 7 + 3$. Least Common Denominator (LCD)The smallest common multiple of the denominators of two or more fractions. It's essential for adding or subtracting fractions with different denominators.For fractions $\frac{1}{3...

Finding a Missing Addend If $A + B = C$, then $B = C - A$ or $A = C - B$. To find a missing addend in an addition sentence, subtract the known addend from the sum. Finding a Missing Subtrahend If $A - B = C$, then $B = A - C$. To find the number being subtracted (the subtrahend), subtract the difference from the minuend (the number from which another is subtracted). Finding a Missing Minuend If $A - B = C$, then $A = C + B$. To find the number from which another number is subtracted (the minuend), add the difference to the subtrahend. Converting Mixed Number to Improper Fraction $W \frac{N}{D} = \frac{(W \times D) + N}{D}$ Multiply the whole number ($W$) by the denominator ($D$), add the numerator ($N$), and place the result over the original denominator ($D$...
