I need help with 10,11,&12
2 answers:
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
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
