#43 is 3 Slices because 12 divided by 4=3
#44 lets work out a bit more. She Practiced 4 hours and 30 minutes each week. There are typically 4 weeks in a month, so we multiply 4 times 4 which is 16. But this isn't our answer because we have the extra half hour. We multiply the half hours times 4, and we have and extra 2 hours on our hands. So this means she Practiced 18 hours each month.
#46 First, You convert everything to inches.
2' 8'=24+8=32 inches.
Divide that 32 in half, and you get 16. 16 inches=16 times 12 =192.
192 over 32 =6.
So in total, 6 boards is your answer :)
