Big Idea For the question we had to come up with 2 strategies I choose Reversibility and Known Facts because they were best for me and The way you do reversibility is for example 172 divide 32 you times 32 with something like 10 which equals 320 and if we half it,it equals 160 then add another 32 which equals 192 so thats the answer in known facts we all know what's 1x32=32 then double that which equals 64 then double that which equals 128 then plus 64 which equals 192 the reason why was because the school can't leave 12 people walking so they had to hire another bus.
