Do the ratios 10 8 and 5 2 form a proportion? yes or no

No

Step-by-step explanation:

pretend that the larger number in the ratio is always 60

10:8 so 10=60

60÷10 =6

6x8=48

so in 10:8 10=60 and 8=48

60-48= 12

in 5:2

5=30

2=12

30-12=18

10:8 and 5:2 when substituted to a real number will not have the same difference so they are not a proportion
