Add a number is it and 3.5.8 together to form three different proportions to write out! Add a number is it and 3.5.8 together to form three different proportions to write out!

Let this number be X
⑴3x=5×8
x=40/3
Scale: 3:5 = 8: (40 / 3)
⑵5x=3×8
x=4.8
Scale: 3:4.8 = 5:8
⑶8x=3×5
x=1.875
Ratio: 1.875:3 = 5:8
May I help you!
In addition, the same number can also be used to form different proportions, such as 4.8
3：4.8=5：8
4.8：3=8：5
3：5=4.8：8
