Answer 1

0.28 and 4.48

Explanation:

c) You have to find the number by which the numbers in the list get multiplied.

If you divide the third number 1.12 by the first 0.07, you get 16. To get from 0.07 to 1.12, the 0.07 was multiplied twice by this number. 16=4*4, so the multiplier is 4.

Now it is possible to calculate the whole series:

0.07 * 4 = 0.28

0.28 * 4 = 1.12

1.12 * 4 = 4.48

4.48 * 4 = 17.92

d) divide the second by the first number:

`\frac {1}{1(1)/(10)} = (1)/((11)/(10)) = (10)/(11)`

So work with factor 10/11 to calculate the series:

11/10, 1, 10/11, 100/121, 1000/1333, ...

g) Divide 7/12 by 2/3 to find 7/8. So the number preceding 2/3 is (2/3) / (7/8) = 16/21 and the numbers after 7/12 are:

(7/12) * (7/8) = 49/96

and

(49/96) * (7/8) = 343/768
