Answer: Yes, because they are similar triangles
Step-by-step explanation:
Let ABC be the right triangle with vertical side of 3 and a horizontal side of 7.
And, right angle at B,
Then, AB = 3, BC = 7 ⇒ AC = √58
Again let, DEF be the right triangle with vertical side of 9 and a horizontal side of 21.
And, right angle at E,
Then, DE = 9, EF = 21 ⇒ DF = 3√58
Thus, in triangles ABC and DEF,
Therefore,
By the property of similar triangles,
Since, in both triangles horizontal sides BC and EF are on X-axis,
Therefore,
The second one is correct

Answer:
Step-by-step explanation:
Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.
Given ratio= elementary schools: middle schools:: 28:16
The ratio can be written as
Now to write into simplest form, we need to divide both numerator and denominator by 4.
∴ elementary schools: middle schools=
Hence, we get simplest ratio of elementary schools to middle schools=
