so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35
so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks
so 35 x 3 =105 35 x 5=175
Ali cooks 175 cookies in 5 hours
0.35 x 1.5 = 0.35(1 + 0.5) courtesy of the distributive property of multiplication over division.
0.35(1) + 0.35(0.5) = 0.35 + 0.175 = 0.525
You know how to arrange these in columnar form, as though you were doing it by hand?
She is incorrect
the GCF of 2, 4 and 8 is 2 (not 8 has she has written)
the GCF of x2, xy and xy4 is x not x2y4
Correct GCF of the 3 terms is 2x

4) .34, 3/8, 50%, 4/7 (this is least to greatest)
Work for 4:
4/7=0.57 3/8=0.37 0.34=0.34 50%=0.5
8) Julexi has 3/4 left and Anthony has 5/8 left
