If i had a pizza, and i ate4/8 of the pizza and my sister ate 3/8 of the pizza, how much pizza did we eat
4/8 + 3/8
To add this fraction, first make sure their denominators are equal. Their denominators are already equal (which is 8). And so we can combine now their numerators while denominator stays the same:
(4 + 3)/8 = 7/8
To find out how much pizza you and your sister ate, you need to add together the portions each of you ate.
You ate 4/8 of the pizza, which can be simplified to 1/2 because both 4 and 8 are divisible by 4.
Your sister ate 3/8 of the pizza.
To add these fractions, we need to have the same denominator. In this case, the least common multiple of 2 and 8 is 8.
So, we multiply the numerator and denominator of 1/2 by 4, which gives us 4/8.
Now we have:
1/2 + 3/8 = 4/8 + 3/8 = 7/8
Therefore, you and your sister together ate 7/8 of the pizza.
