Answer:
The answer to your question is 2 1/4
Step-by-step explanation:
Data
First day = 3/4
Second day = 1 1/8
Third day = 1 1/2
Process
1.- Find the difference between the distances
1 1/8 - 3/4 = (8 + 1)/8 - 3/4
= 9/8 - 3/4
= (9 - 6)/8
= 3/8
1 1/2 - 1 1/8 = (2 + 1)/2 - (8 + 1)/8
= 3/2 + 9/8
= (12 + 9) / 8
2.- Find the distance she ran the fifth day
5th = 1 1/2 + 3/8 + 3/8
= 3/2 + 3/8 + 3/8
= 12/8 + 3/8 + 3/8
= 18/8
= 9/4
= 2 1/4
B.
The first number minus the 2nd number will close off the distance.
(5-2i) ( 5+2i) = (5^2) - ((2i)^2) = 25 - 4i^2
= 25 - 4(-1) = 25 +4 = 29 + 0i
