How can you convert .333 into a fraction?
First, look what the final place of the number is (in this case the last number is in the thousandths). So, your denomanator is 1,000. The numerator now is just the number without any decimals. So, the fraction is 333 over 1,000 (333/1,000)
Name three fractions whose decimal equivalent is 0.25 and explain how you know each fraction is equivalent to 0.25?
0.25 = 25/100 = 1/4 = 10/40. All three fractions are the same because the denominator is four times the numerator, and the first is the same as 0.25 because if you divide 25.0 by 100, you move the decimal point left two places and get 0.25. from the decimal of the fraction to the denomanator divided from the decimal and multiplied by the fractio sence equal the answer and youll get it!
