Math problems: decimal Definition Types Fraction Test

Types Fraction Test Definition a fraction with an unwritten denominator of 10 or some power of 10, indicated by a point Examples: 0.53,0.3,0.22

Types Fraction Test Definition Types of decimals 1.Repeating decimals: It goes on forever repeating the same digits over and over. ex: , , terminating decimal: A terminating decimal is a decimal that stops. ex: 1/8 = 0.125, 1/50 =0.02, 1/32 = irrational decimal: An irrational decimal is one that does not terminate or repeat. ex: pi, the square root of 2, any other non-perfect square roots

Types Fraction Test Definition Terminal decimal: 0.25 Repeating decimal: 0.666… x= x= x-x=6 x=6/9 25/100=1/4 Irrational decimal: A non-terminating AND NON-REPEATING decimal CANNOT be converted to a fraction You should probably just memorize some of the more basic repeating decimals, like = 1 / 3 and = 2 / 3
