how about this one ???

RPM   =  Pages read / number of minutes  ....so we have

[ 8 + 1/3]  / 5   =

[25/3] / [5 / 1]   =

25/3  *  1/5   =

25/5 * 1/3  =

5 * 1/3   =

5/3   = 1 + 2/3  pages per minute

8 1/3 pages over 5 minutes is equal to x pages in 1 minute.

All that needs to be done is divide 5 minutes by 5 to equal 1 minute, and divide 8 1/3 by 5, too. 8 1/3 divided by 5 is 1 1/3.

Carlos reads an average of 1 1/3 pages per minute.

carlos reads 8 and 1/3 pages in 5 minutes what is his average reading rate in pages per minute

(81/3) / 5=1 2/3 pages per minute.
