For question number 3 you would add 24+13+38. And that would give you 75. Making the fraction 75/100, in simplest form it would be 3/4. So the answer for number 3 is 3/4
For number 4: you add 0.5 and 3/10 together, but you can’t add a decimal and a fraction so we will convert the decimal to a fraction, 0.5 is equivalent to 1/2 so we will do 1/2 + 3/10. To add you have to find the most common multiple which would be 10. So now the equation is 5/10 + 3/10. Now all you have to do is add the numerators so 5/10+3/10=8/10. 8/10 in its simplest form is 4/5. Your final answer should be 4/5.
