Respuesta :
To solve you multiply 4x5=20 and 3x7=21. The numbers are not equal, so they are not proportional. (Hope this helps!)
Answer:
No they are not proportional.
Step-by-step explanation:
If you make the ratio into a fraction it looks like this
4/7 and 3/5
Now you cross multiply
4*5 and 3*7
Now you have 20 and 21
Those numbers are unequivelent
So they are not proportional
