on your calculator, divide 6 by 7.

then compare 252/294, 312/378 and 102/133.

only one of them should give you the same answer as 6/7

anonymous · Answer

I could divide all of them by 6 and 7

anonymous · Answer

you could.

only one of them would give you 1 as an answer since (6/7)/(6/7) = 1
