Answer: 10 7/18
Find the least common denominator.
4 5/9 = 4 10/18
5 5/6 = 5 15/18
Add up the fractions.
4 10/18 + 5 15/18 = 9 25/18
Turn 9 25/18 into a mixed number.
10 7/18
To add 1/2 and 5/12, make both fractions have the same denominator:
1/2 is the same as 6/12, so 6/12+5/12=11/12
Thus, B is right.
First you take 7143-6997 to get her units used( it’s 146) since you know that the first 100 units cost 24p per unit so take 100 Times 24 p to get 2400p then take the remaining 46 units times 16 to get 384p.
Add 2400p+384p to get 2784p for her bill
Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.
If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).
Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.
c^2 = a^2 + b^2
where c is the total displacement from the starting point to the end point
a is the distance he walks up north
b is the distance he walks to the west
c^2 = 100^2 + 100^2
c^2 = 10,000 + 10,000
c^2 = 20,000
c = 141.42 meters
Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.
100 meters + 100 meters - 141.42 meters = 53.58 meters

One fourths divided by three is one twelfth. When dividing fraction remember to use reciprocation. 1/4 divided by 3 = 1/4 x 1/3 = 1/12. Hope this helps!
