PLEASE HELP!!!! Identify the mistake and use the correct answer to the problem!!!

Answer:
1 [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
the denominators must be the same so, since 4 goes evenly into 24 we can create an equivalent fraction from 3/4 to 18/24 (multiply numerator and denominator by 6)
now you can add:
[tex]\frac{15}{24}[/tex] + [tex]\frac{18}{24}[/tex] = [tex]\frac{(15+18)}{24}[/tex] = [tex]\frac{33}{24}[/tex]
since the numerator is larger than the denominator this is called an improper fraction and can be changed into a mixed number by dividing 24 into 33
24 goes into 33 one time with a remainder of 9
so 33/24 = 1 [tex]\frac{9}{24}[/tex] wherein 9 and 24 can each have a 3 factored out to make it fully simplified
9÷3 = 3
24÷3 = 8
final answer is 1 [tex]\frac{3}{8}[/tex]
Answer:
11/8 is the correct answer
Step-by-step explanation:
15/24 + 3/4
Reduce the fraction 15/24 to lowest terms by extracting and canceling out 3.
=5/8 +3/4
Least common multiple of 8 and 4 is 8. Convert 5/8 and 3/4 to fractions with denominator 8.
= 5/8 + 6/8
since 5/8 and 6/8 have the same denominator, add them by adding their numerators.
= 5 + 6/8
Add 5 and 6 to get 11.
=11/8
here is why 9/14 is wrong
