Respuesta :

the ratio of striped ties to solid ties is 1:3

If you have 7 striped ties and 21 solid ties and they're asking for the ratio of striped to solid, then you would write it as

7:21

And if you want it simplified, you would divide 7 by 7 and 21 by 7. So,

7/7= 1

21/7= 3

The answer is 1:3
