Answer :
so for the ratios to be equivilent, the fractions must be equal
conver teh denomators to the same number (denomator is the bottom number)
7. 2/11 and 11/10
it's really easy to see that this is not equivlent because 2/11 is less than 1 and 11/10 is more than 1 so they are not equivelent fractions/ratios
8. 4/11 and 11/9
this is also obvious because 4/11 is less than 1 and 11/9 is more than 1 so they are not equivilent fracitons/ratios
9. 2/5 and 4/3
this is very obvous because 2/5 is less than 1 and 4/3 is more than 1 so they are not equivilent
10. 5/11 aand 11/8
this is obvious because 5/11 is less than 1 and 11/8 is more than 1 so they are not equivilent
11. 3/5 and 12/7
they are obviously not equivilent because 3/5 is less than 1 and 12/7 is more than 1 so they they are not eequivilent
12. 11/3 and 9/11
11/3 is more than 1 and 9/11 is less than 1 so they are not equivilent
none of them are equivilent
