The video tutorial explains how to add and subtract fractions with like denominators. It begins by introducing the concept of subtracting fractions and breaking down non-unit fractions into smaller parts. Using examples like pizza and oranges, the tutorial demonstrates how to add and subtract fractions by focusing on the numerators while keeping the denominators constant. The key takeaway is that the number of pieces in a whole does not change, so denominators remain the same during these operations.

What is the key concept when adding or subtracting fractions with like denominators?

• Only change the numerators

• Only change the denominators

• Change both numerators and denominators

• Change neither numerators nor denominators

When adding fractions like 2/6 and 1/6, what should you do with the denominators?

• Subtract them

• Keep them the same

• Add them together

• Multiply them

In the pizza example, if you eat 2/6 and your friend eats 1/6, how much pizza is eaten in total?

• 1/6

• 4/6

• 3/6

• 2/6

How do you determine the numerator when subtracting fractions like 2/6 and 1/6?

• Multiply the numerators

• Subtract the numerators

• Divide the numerators

• Add the numerators

In the orange example, if Mikayla eats 7/12 before lunch and 4/12 after lunch, how much of the orange does she eat in total?

• 10/12

• 9/12

• 11/12

• 12/12
