Astray dog ate 6 of your muffins. that was four thirds of all of them. with how many did you you start?

Step-by-step explanation:

The total number of muffins was  

40

.

Explanation:

You can translate the important parts of the sentence from English to math (say that  

n

is the total number of muffins):

A stray dog ate  

6



6o f your muffins.

=



That was

3

10



3

10

×



of

n



all of them!

Now copy down the equation and solve for  

n

:

12

=

3

10

n

12

10

=

3

This means that the total number of muffins was
