Last​ winter, the ratio of days with snow to days with no snow was 1.42. Write this ratio as a fraction in simplest form.

Answer 1

A ratio between two "things" requires two numbers in the form a : b
you gave just one number 1.42

Did you mean the ratio of days with snow to days with no snow is 1.42 : 1 ?
if so, then
1.42 : 1
= 142 : 100
= 71 : 50 or , if you want it in fraction form, 71/50

If not, repost using correct statements.
