It is 5 you just have to count
Yes it is because 1/4 + 1/4 =2/4 and 2/4 equals 1/2
1/3 * 7/9 kg = (1 * 7)/(3 * 9) kg = 7/27 kg
He used 7/27 kg of sugar.
The slope can be found by using the formula:

Where
m
is the slope and (
x

,
y

) and (
x

) are the two points on the line.
Substituting the values from the points in the problem gives:
