anonymous · Answer

i know that the five 1/4 pages = 1 1/4

anonymous · Answer

but is it the nine 1/20 = 9/20? and then what?

anonymous · Answer

Sum all of them.

anonymous · Answer

am i correct on the 9/20?

anonymous · Answer

is 9/20+5/4+2/5=21/10

anonymous · Answer

opps sorry
9/20 plus 2/5 = 17/20

anonymous · Answer

17/20 plus 5/4 = 42/20?? am i doing this right?

anonymous · Answer

yes.. and i simplify 42/20 .. i think i got it

anonymous · Answer

Yeah is right

17/20+5/4=(17*4+20*5)/(20*4)=(68+100)/80=(168)/80

Then take the half of both

84/40

half again

42/20

Half again

21/10
