Question

Is 21/50 greater or less than 42%

Answer 1

According to my calculations, the LCM of the two denominators is 50. Therefore, since 50 goes into 50 a total of 1 times, you would multiply the top and bottom of the first fraction by 1. And since 1 goes into 50 a total of 50 times, you would multiply the top and bottom of the second fraction by 50.  Now that the denominators are the same, you can simply compare the numerators to determine which fraction is greater. Since 21 is less than 2100, 21/50 is less than 2100/50. Therefore the 1st entry (21/50) is less than the 2nd entry (42).
