13=10+3 so
13-7=3+10-7=3+3=6
#7 is A
For # 5 & 6 is there a multiplication sign between the numbers or is supposed to be a power or something else?
5/11
11 goes into 5 zero times (0.)
11 goes into 50 four times with a remainder of 6 (0.4)
11 goes into 60 five times with a remainder of 5 (0.45)
11 goes into 50 four times with a remainder of 6 (0.454)
11 goes into 60 five times with a remainder of 5 (0.4545)
The answer is .45 with a bar on top of both the 4 and the 5.
You have to add and divide for the mean(average) so add all of them up and then divide by 3 :)
