Answer 2

Answer:

1.  (1,3,7,9,21, 63)

2.   54

  6   *    9

2 * 3 * 3 * 3

2 * 3³

3.   4/9

4.   12/1

5.  41/4 = 10 1/4

6.  875/1000 = 7/8

7. 2/3 vs 5/10     Cross Multiply numerator and denominator on each side

    20 vs 15    

Therefore 2/3 is larger than 5/10

8.  Common Denominator for 3/8 and 1/12  is 24

17. 4/44 were born in Indiana therefore 40/44 were NOT born in Indiana and that reduces to 10/11

18.  112 miles in 5 5/6 hrs.....     112 divided by 5 5/6 = 19 1/5 miles

19.  1  2/3 divided by 2 = 5/6 hours

20. 5 1/2 + 6 1/4 = 11 3/4  * 8 = $94.00
