Answer:
No
Step-by-step explanation:
In order to know whether ratios are equivalent, you have to convert them intro fractions first, then cross multiply.
The fraction form of 11:20 is [tex]\frac{11}{20}[/tex]
The fraction form of 1:2 is [tex]\frac{1}{2}[/tex]
Next is to cross multiply both to see if they have equivalent (the same) values.
[tex]\frac{11}{20}[/tex] = [tex]\frac{1}{2}[/tex]
11 x 2 = 20 x 1
22 ≠ 20
Therefore, 11:20 and 1:2 are not equivalent.
