Well, 1 jar = 26 ounces
So, to find out how many cups are in 4 jars, I am going to multiply, 26×4= 104, So there are 104 ounces in 4 jars but to find out how many cups are in 4 jars, I need to see how many ounces are in 1 cup, Which there are 8 ounces in 1 cup, So to find out how many cups are in 4 jars, I need to divide 104 ounces ÷ 8 ounces= 13 cups
So there are 13 cups in 4 jars
I hope this helped :)
