Simple, 7/12 is greater than 1/3 because 7/12=0.58333 and 1/3=0.333, 0.58333 is greater than 0.333. That is how I know that 7/12 is greater than 1/3. I know that 1/3 is less than 2/3 because 1/3=0.333 and 2/3=0.666, 0.333 is less than 0.666
A=1 and 2
B=2 and 4
C=1,2,7 and 14
D=1,2,4,and 8
A
100+89.50×36
=3,322
b
3,322−2,900
=422
c
2,900÷89.50
=33
