Keeping in mind that, there are 12 months in a year, therefore, 7 months is really just 7/12 of a year.
Answer:
2. -1/2
4. 3/2
Step-by-step explanation:
Gradient = (Y1 - Y2)/(X1 - X2)
2.
Point 1: (4, -1)
Point 2: (-2, 2)
Gradient = (-1 - 2)/(4 - (-2)) = -3/6 = -1/2
3.
Point 1: (4, 6)
Point 2: (-4, -6)
Gradient = (6 - (-6))/(4 - (-4)) = 12/8 = 3/2
Here, we want to select which of the fractions are rational
To get this, we need to understand what rational numbers are
Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero
From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero
This means all the given fractions are rational
2/5, 2/6, 1/7, 3/8, 2/9, 5/10, 1/11, 3/12, 2/15
