Answer:
The proportion is true.
Step-by-step explanation:
We are given the following proportion and we are to determine whether it is a true proportion or not:
[tex] \frac { 15 } { 3 } = \frac { y } { 7 } [/tex]
Finding the value of y:
[tex]y = \frac{15}{3} \times 7[/tex]
[tex]y=35[/tex]
So now we have [tex] \frac { 15 } { 3 } = \frac { 35 } { 7 } [/tex]
Checking if it is a true proportion:
[tex] \frac { 15 / 3 } { 3 / 3 } = \frac { 5 } { 1 } [/tex]
[tex] \frac { 35 / 7 } { 7 / 7 } = \frac { 5 } { 1 } [/tex]
Since the simplified fractions are equivalent, therefore the proportion is true.
