1 whole pizza is equal to 8/8. If Louis eats 6/8 then there should be 2/8 left, if your teacher wants it simplified then you will divide both the numerator and the denominator by 2 giving you a fraction of 1/4.
Louis has eaten 6/8 of a pizza, which leaves 2/8 or simplified as 1/4 of the pizza remaining. This is a basic arithmetic operation involving fractions.
When Louis eats 6/8 of a pizza, he leaves behind 2/8 of the pizza, which can also be simplified to 1/4. To find this, you subtract the amount eaten from the whole pizza (1):
Whole pizza: 1 (or 8/8 to use a common denominator)
Amount eaten: 6/8
= Amount left: 2/8, which simplifies to 1/4 (divide both numerator and denominator by 2)
This numerical problem requires an intuitive sense to understand fractions, and in this case, picturing the fraction of the pizza left is similar to understanding how many quarters are in a dollar. Louis, just like Jenny in the chocolate problem, deals with dividing amounts and understanding the remainder which is a key concept in dealing with fractions and basic arithmetic.
After Louis ate 8 6 of the pizza, 8 2 remains, which simplifies to 4 1 . Thus, 4 1 of the pizza is left over.
