1. 15 / 1/3
When dividing, the second fraction flips over .
15* 3/1= 45/1= 45
2. 24 / 1/6
24*6= 144
4. 7/12 / 1/3
7/12*3/1
Cross out 3 and 12, divide by 3
12/3= 4
3/3= 1
7/4* 1/1. Multiply the numerator together. Multiply the denominators together.
7*1= 7
4*1= 4
7/4 or 1 3/4

Answer:
the two selected are correct.
Step-by-step explanation:
A relation is a function only if it relates each element in its domain to only one element in the range. When you graph a function, a vertical line will intersect it at only one point. You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function. The best way to find out whether an equation represents a function or not is by graphing the equation and then applying the vertical line test. Graph the two-variable equation on graph paper. For a straight line this means graphing two or more points on the line and connecting the dots.
