About this deck

Fractions and decimals are foundational math skills tested from elementary school through standardized tests. This deck covers simplifying fractions, adding and multiplying them, and converting between fractions and decimals. You'll also review terminating vs. repeating decimals, common denominators, and decimal place value. A must-have refresher deck for building strong numeracy fundamentals.

A number representing a part of a whole, written as numerator over denominator
The top number in a fraction, indicating how many parts are taken
The bottom number in a fraction, indicating the total number of equal parts
A fraction where the numerator is smaller than the denominator
A fraction where the numerator is greater than or equal to the denominator
A number combining a whole number and a proper fraction
Divide the numerator by the denominator; the quotient is the whole number and the remainder becomes the new numerator
A fraction that represents the same value as another, despite different numbers
Divide the numerator and denominator by their greatest common factor
Find a common denominator, then add the numerators
Multiply the numerators together and the denominators together
Multiply the first fraction by the reciprocal of the second
The fraction flipped, with numerator and denominator swapped
A number that uses a decimal point to represent values less than one
Divide the numerator by the denominator
Write the decimal digits over the appropriate power of 10, then simplify
A decimal that ends after a finite number of digits
A decimal in which one or more digits repeat infinitely
Look at the hundredths digit; round up if 5 or greater, otherwise round down
The value of a digit based on its position relative to the decimal point
Line up the decimal points and add as with whole numbers
Multiply as whole numbers, then place the decimal point based on the total decimal places in both factors
Move the decimal point in the divisor and dividend to make the divisor a whole number, then divide normally
A shared multiple of the denominators of two or more fractions
The smallest common multiple of the denominators of two or more fractions
Convert them to a common denominator or cross-multiply
A fraction with a numerator of 1, such as 1/4
Both represent parts of a whole; every fraction can be expressed as a decimal
0.75
1/2
