Brut [27]3 years ago

Answer:

Alright, so we have to find the LCM of 2.75 and 3.5.

A good start would be to multiply them together to get 9.625, but we want a whole day!

This would be every 77 days :)

Change the fraction to a improper fraction.

11/9 + 10/9

Since they have the same denominators you can add them.

11/9 + 10/9 = 21/9

The answer is 21/9

Hope this helps :)
