Question

I need help with 10,11,&12

Answer 1

10) 2/3 * 7/4 = 14/12 = 7/ 6

11) 7/11 + 8/11 = 15/11 = 1 4/11

12) 38,220 ÷ 15 = 2,548

Answer 2

10) Cross simplify:

2/2 = 1

4/2 = 2

1/3 x 7/2 = 7/6, or 1 1/6

-----------------------------------------------------------------------------------------------------------------

11) They have the same denominators, so just add across

7 + 8 = 15

15/11 = 11/11 + 4/11

11/11 = 1

1 4/11 is your answer

-----------------------------------------------------------------------------------------------------------------

12) 38220/15 = 2548

hope this helps
