Answer 1

Step-by-step explanation:

I am not allowed to answer more than 3 questions.  So I will do the first 3.

15a. i)  (2/3) = 4/9

      ii)  (2/3) = 8/27

      iii)  (2/3) = 16/81

  b.  The product is small because you are finding the fraction of a fraction.

16.  Compared to the factors, the product is less than each fraction.  This is because, as stated above, you are trying to find a fraction (a part of the whole) of another fraction.  When you multiply a whole number by a fraction, the whole number decreases.  The same applies to a fraction.

17a.  0.4 × 0.3 = 0.12

  b.  0.4 = 4/10 = 2/5

       0.3 = 3/10

       3/10 × 2/5 = 6/50
