The 5 rational are 91/150 , 92/150 , 93/150 , 94/150 , 95/150
Step-by-step explanation:
We have to fine 5 rational numbers between
3/5 and 2/3
First we have to make the denominator same
3/5= 3/5 ×3/3 = 9/15 =9/15×10/10 =90/150
2/3 = 2/3×5/5 = 10/15 = 10/15×10/10 = 100/150
The 5 rational numbers are
91/150 , 92/150 , 93/150 , 94/150 , 95/150

Which graph shows a dilation?
answer:
now correct me if i am wrong but i think that graph number one is the graph showing a dilation
now i totally forgot now to explain dilations in graphs but if you need anymore help, feel free to ask me!
hope this helps :)
The graph that shows a dilation is the graph on the left which is the 2nd option in the given figure.
A dilation is a transformation that changes the size of an object, but not its shape. The scale factor is a number that tells you how much the object is being enlarged or shrunk. A scale factor of 2 means that the object is being enlarged twice as large, while a scale factor of 0.5 means that the object is being shrunk to half its size.
The graph that shows a dilation is the graph on the left. The scale factor of the dilation is 2, so the object is being enlarged twice as large. The other two graphs do not show a dilation because the objects are being changed in shape.
The graph on the right shows a rotation of the square by 90 degrees. The graph in the middle shows a stretching of the square horizontally. Neither of these transformations are dilations because they change the shape of the object.
