Otis made 1 3/5 cups of oatmeal he put 2/5 cup of oatmeal into each bowl how many bowls of oatmeal did Otis make? use an equation to solve e problem
If Otis has 1 3/5 cups of oatmeal
And 2/5 cups go into each bowl of oatmeal,
Then we want to find how often 2/5 cups goes into 1 3/5 cups.
Let n be the number of bowls of oatmeal.
Let V be the total volume of oatmeal, and V = 1 3/5 cups
Let v be the volume of each cup of oatmeal, and v = 2/5 cups.
Then our equation is: V = n*v
i.e. the total volume is the number of cups times the volume of each cup
So V = n*v
Using V = 1 3/5, and v = 2/5, then
1 3/5 = n*(2/5) multiply each side by 5.
5 + 3 = n*2
8 = 2n
n = 4
Therefore the number of bowls of oatmeal made is n = 4
