Divide both numbers by 13/90
13/90x = 130
÷13/90 ÷13/90
x= 900
That would be 20 x 19 x 18 which equals 6840.
After first place is chosen, 19 spots left and so on.
The answer is 6840 ways.
(4*10,000)+(8*1,000)+(2*100)+(4*10)+(3*1)
40,000+8,000+200+40+3=48,243
That is one way. You can also do this using exponential form!
Hope that helps
Answer:
-2/9
Step-by-step explanation:
Make each fraction have a like denominator
7/9 * 8/8= 56/ 72
7/8 * 9/9 = 63/72
18 + 14 + (56+63)/72
32 + 119/72
32 + 1 + 47/72
33 and 47/72
