To solve this type of problems, the easiest way to compare is to change them all to fractions, or to decimals, whichever is easier for you.
For the first one, change them all to decimals, A. 525/1000=0.525 B. 3/4 = 0.750 C. 0.55 =0.550 Thus it will be obvious, whether you'd like smallest to biggest or otherwise.
For the second problem, A. 3.85=3.850 B. 3 5/8 = 3.625 C. 3.805 = 3.850
A. turn all fractions into decimals or all decimals into fractions; I've decided to turn all fractions into decimals
525 ------- = 0.525 1000
3 -- = 0.75 = 0.750 ~ (add a zero at the end to make the decimal places 4 equal with 0.525)
0.55 = 0.55 = 0.550 ~<span>(add a zero at the end to make the decimal places equal with 0.525 and 0.750) </span> <span> Answer to Problem 'a':</span>
Smallest = 0.525 = 525 ------- 1000
Middle = 0.550 = 0.55
Largest = 0.750 = 3 -- 4
b. <span>turn all fractions/mixed fractions into decimals or all decimals into fractions; I've decided to turn all fractions/mixed fractions into decimals </span> 3.805 = 3.805
3.85 = 3.850 ~ ( <span>add a zero at the end to make the decimal places equal with 3.805) </span> 3 4/5 = 80 ----- = 0.80 =0.800 ~ (add a zero at the end to make the decimal 100 places equal with 3.805 and 3.850)
