Answer:
7/15
Step-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 denominator
So times both denominators of the fractions together; 5x3=15
Now find 1/3 of 15. Do this by dividing 15 by 3. This equals 5.
So 1/3 is equal to 5/15
Now do the same for 1/5. 15 divided by 5, this equals 3.
So 1/5 is equal to 3/15
Now that we know that the whole pizza is 15/15
We 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 = x
x = 7/15
So 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.
