Idon't understand this one. i am dividing 36 and 150 which i think is right and i am getting 4 remainder 6. what am i doing wrong?

(150in / 1)(1ft / 12in)(1yd / 3ft)     start out with a simple conversion formula

(150in / 1)(1ft / 12in)  = 12.5ft     do the first part of the equation 

(12.5ft)(1yd / 3ft) = 4.166666yd     do the second part of the equation 

hope this helps :)

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!
