Tom bought a pizza. He ate 1/3 of the pizza and gave some of it to his brother. He was then left with 1/5 of the pizza. What fraction of the pizza did Tom give his brother?
Accepted Solution
A:
Answer:7/15Step-by-step explanation:first recognise that 3/3 is a whole pizza and so is 5/5.Secondly make all the numbers to have the same denominatorSo times both denominators of the fractions together; 5x3=15Now find 1/3 of 15. Do this by dividing 15 by 3. This equals 5.So 1/3 is equal to 5/15Now do the same for 1/5. 15 divided by 5, this equals 3.So 1/5 is equal to 3/15Now that we know that the whole pizza is 15/15We minus 1/3 from 15. 15-5=10. So we now have 10/15 left.now we know that 'x' is representative of the amount of pizza Tom gave to his bother.10/15 - 3/15 = xx = 7/15So out of the whole pizza (15/15), tom ate 5/15 and was left with 3/15 meaning he gave 7/15 to his brother.
