Pete ate one fourth of a pizza and Paula ate one third of a pizza . What fraction of the pizza did they eat?
1/4 + 1/3, right?
just add the fractions, using a common denominator.
To find out what fraction of the pizza Pete and Paula ate, we can add their individual fractions together.
Pete ate one-fourth of the pizza, which can be written as 1/4.
Paula ate one-third of the pizza, which can be written as 1/3.
To add these fractions, we need a common denominator. The least common multiple (LCM) of 4 and 3 is 12.
Now let's convert the fractions to have a denominator of 12:
Pete's fraction becomes 3/12 since multiplying both the numerator and denominator by 3 gives us 3/12.
Paula's fraction becomes 4/12 since multiplying both the numerator and denominator by 4 gives us 4/12.
Now we can add the fractions:
3/12 + 4/12 = 7/12
Therefore, Pete and Paula together ate 7/12 of the pizza.
