@hartnn

hartnn (hartnn):

as per Michele's hint, the 2 1/2 is divided into 20 1/8ths. so what does = 20/8? 7 1/2 or 6 2/3 ??

OpenStudy (petlovers123):

is it 7 1/2

hartnn (hartnn):

7 1/2 = 7+ 1/2 = (7*2+1)/2 = 15/2 so no

OpenStudy (petlovers123):

so im assuming 6 2/3

hartnn (hartnn):

why assume when you can be sure? 6+2/3 = (6*3+2)/3 = (18+2)/3 = 20/3

OpenStudy (petlovers123):

ok so is it D) There are 6 2/3 two and one-halves in 3/8

hartnn (hartnn):

nope

OpenStudy (petlovers123):

B

OpenStudy (petlovers123):

B) There are 6 2/3 three-eights in 2 1/2
