7/9 * 3/5 but this is the same as 7/3 * 1/5 because of cancellation; therefore, the answer is 7/15.

7/9 X 3/5 = 21/45
Divide both numerator and denominator by 3
= 7/15.

multiply tops together and bottoms together
21/45 which you can then divide out a 3 from each.
7/15

7X3 = 21
....... ------
9X5 = 45
the answer is 21/45 however this is not reduced to the least common denominator, 21 and 45 have a comon factor of 3, if you divide both by 3 then:
21/3 = 7
....... ------
45/3= 15
and if you want to convert it to a decimal its .4666666666666666666666666666666666666666666

a million: all of it cancels: its consequence is a million -> the p^2 cancel eachother leaving 2; the 2p+a million and the 4p+2 cancel to a million/2 because of the fact the 4p+2=2(2p+a million). then you certainly offered 2/2 = a million 2 : this one is the comparable in yellow: 4r+8 = 4(r+2). and it cancels with r+2 to 4/a million and the 6 and 18 cancel to a million/3 leaving the top result 4/3 * r 3: first step: d^2+8d+sixteen=(d+4)^2 this cancels with "over d+4" leaving: a million over d^three times d^2 and this cancels to the top result a million/d
