Renaldo will write StartFraction 3 over 20 EndFraction as a decimal. Which of the following methods should he use?
Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Multiply the fraction by One-fifth to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Multiply the fraction by StartFraction 33.3 over 33.3 EndFraction to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
Multiply the fraction by 33.3 to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
To write a fraction as a decimal, you can multiply the fraction by a power of 10 so that the denominator becomes 10, 100, 1000, etc. In this case, you want to write the fraction 3/20 as a decimal.
Multiplying the fraction by 5/5 or one-fifth does not change the value of the fraction.
Multiplying the fraction by 33.3/33.3 will not give a denominator of 100.
Multiplying the fraction by 33.3 will not give a numerator of 100.
Therefore, Renaldo should use the method of multiplying the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
