Common Fraction Decimal Percents Flash Cards Write these fractions on the front of the cards: 1/8, ¼, 3/8, ½, 5/8, ¾, 7/8, 1/6, 1/3, 2/3, 5/6, 1/10, 1/5, 3/10, 2/5, 3/5, 7/10, 4/5, and 9/10. All fractions are in lowest terms, although you might have to know the equal fractions as well! Then on the back of the card write the correct decimal and percent (These two numbers are written in almost the same way, look at what the differences are between a decimal and percent). Practice with your flash cards! You will be tested on these!
