The requirement is that every element in the domain must be connected to one - and one only - element in the codomain.
A classic visualization consists of two sets, filled with dots. Each dot in the domain must be the start of an arrow, pointing to a dot in the codomain.
So, the two things can't can't happen is that you don't have any arrow starting from a point in the domain, i.e. the function is not defined for that element, or that multiple arrows start from the same points.
But as long as an arrow start from each element in the domain, you have a function. It may happen that two different arrow point to the same element in the codomain - that's ok, the relation is still a function, but it's not injective; or it can happen that some points in the codomain aren't pointed by any arrow - you still have a function, except it's not surjective.
Answer:
m/1 < m/6
m/3 + m/5 < m/7 + m/8

I think you mean "Equivalent ratios" if that makes sense, but anyways in order to find Equivalent ratios, you have to either multiply or divide both the numerator and denominator of a given ratio by the same number.
For example: Create a table with the numbers of boys and girls
1. Boys: 3
2. Girls: 5
Next set this as a fraction like this
1. 3/5
Then to find equivalent ratios, multiply both numbers by two and you should get
6/10 (because we multiplied the 3/5 by 2)
Next write 6/10 along the chart of boys and girls
(Write them as fraction like this: 3/5 and 6/10)
Ratio of:
Boys: 3, 6
Girls: 5, 10
and there you have found an equivalent ratio.
45:60*20=15 miles the distance she traveled at 45 mph
18-15=3 miles she traveled at 20 mph
3/20=0.15 hours she traveled to reach the work
0.15*60=9 minutes
20+9=29 minutes she traveled to work
7:15+29=7:44
Kenya arrive at work at 7:44
