4.5 Fractions and Decimals 383- Sometimes, when finding the decimal equivalent of a
fraction, the division process ends because a
remainder of 0 is obtained. We call the resulting
decimal a decimal. - Sometimes, when we are finding the decimal
equivalent of a fraction, the division process never
gives a remainder of 0. We call the resulting decimal a
decimal. - If the denominator of a fraction in simplified form has
factors of only 2’s or 5’s, or a combination of both, it
can be written as a decimal by multiplying it by a
form of. - a. Round 0.3777... to the nearest hundredth.
b. Round 0.212121... to the nearest thousandth.- a. When evaluating the expression ,
would it be easier to work in terms of fractions or
decimals?
b. What is the first step that should be performed to
evaluate the expression?
