What is 63.5% written as a decimal? A. 0.0635 B. 0.635 C. 6.35 D. 635
jek_recluse [69]

Answer:

B. 0.635

Step-by-step explanation:

Having a percent means its out of 100 so we can turn the percent into a fraction. 63.5/100


We cant have a decimal in our fraction, so we can multiply by 10 to get rid of it. (63.5*10)/(100*10)=635/1000


Since the denominator is a multiply of 10, we can convert the numerator into a decimal. .635

So your answer would be B. 0.635
