Answer:
1/12
Step-by-step explanation:
So you start with an equation. 2/3 plus 1/4= ?.
Step 1: Find a common donominator.
Count by each number until they meat up.
3 6 9 12
4 8 12
Step 2: Multiply.
Basically, make sure that if you do something to the bottom you do the same to the top. You have
[tex]\frac{2}{3}[/tex] = [tex]\frac{?}{12}[/tex]. 3 times 4 is 12. 2 times 4 is 8. Your new fraction is [tex]\frac{8}{12}[/tex].
[tex]\frac{1}{4}[/tex] = [tex]\frac{?}{12}[/tex]. 4 times 3 is 12. 1 times 3 is 3. Your new fraction is [tex]\frac{3}{12}[/tex].
Step 3: Just Add!
[tex]\frac{8}{12} + \frac{3}{12}= \frac{11}{12}[/tex]
Step 4: Answer the question! The question asks "How much cake is left. You know that a whole cake is [tex]\frac{12}{12}[/tex]. So, [tex]\frac{12}{12} -\frac{11}{12} = \frac{1}{12}[/tex]
