A stray dog ate 25 of your muffins that was 5/6 of all of them with how many did you start?

30 = total muffins

Step-by-step explanation:

To determine how many muffins were eaten, we take the total muffins times the fraction that were eaten

eaten muffins = total muffins * fraction

25 = total muffins * 5/6

Multiply each side by 6/5

6/5*25 = total muffins * 5/6*6/5

30 = total muffins
