In art mr jocelyn have everyone 1 foot stick to measure and cut vivian measured and cut her stick into five equal pieces. scott measured and cut his into 7 equal pieces. scott said to vivian the total length of my stick is longer than yours because i have 7 pieces and you only have 5. is scott correct?

This is not correct because they each started with the same size piece of stick.  Scott's pieces are shorter than Vivian's pieces because the same starting size was broken into 7 pieces where Vivian's was only broken into 5 pieces.  1/5 is bigger that 1/7.     The question is confusing at the beginning.  It is not grammatically correct.  

Ithink it is 7. 16
