2 1/4 times 8?

OpenStudy (lochana):

\[2\frac{1}{4}* 8 = \frac{9}{4}*8 = 18\]

OpenStudy (flygirlmandi):

why the extra times 8=18 ?

OpenStudy (lochana):

no. you need to convert it into mixed fraction. it will be 9/4 now you can multiply 9/4 and 8 (9/4)8 = 18

OpenStudy (lochana):

mixed fraction = 2 1/4 improper fraction = 9/4
