The food lasts #22.3# or #22# days.

We know she feeds her dog #0.3# pounds #2# times a day so we multiply #0.3# by #2# to know how much she feeds in one whole day

#0.3 xx 2 =0.6#

All we need to do now is divide the big number by the smaller one.

#13.4 -: 0.6 = 22.3#

To check the answer you would then take your answer #22.3# and how much shes feeding him a day #0.6# and multiply them together:

#22.3 xx 0.6 = 13.38# (When we round #13.38# up we get #13.4#)

This answer is #13.4#. Which is how much is in the whole bag, this is how we know our answer (#22# days) is correct!
