Question

B. To make salad dressing for the fruit salad, Mrs. Santos uses 2/4 cup oil, 1 cup orange juice, and 3/4 cup honey. How many cups of salad dressing does this make? Explain how you found your answer.

Answer 1

Add all

`\\ \rm\rightarrowtail (2)/(4)+(3)/(4)+(4)/(4)`

`\\ \rm\rightarrowtail (2+3+4)/(4)`

`\\ \rm\rightarrowtail (9)/(4)`

`\\ \rm\rightarrowtail 2(1)/(4)cups`

Answer 2

`\sf 2 \frac14 \ cups`

Explanation:

Add the amounts together:

`\sf \implies \frac24+1+\frac34`

Convert the whole number 1 into a fraction with denominator 4:

`\sf \implies \frac24+\frac44+\frac34`

As all the denominators are the same, we can simply add the numerators:

`\sf \implies \frac{2+4+3}4`

`\sf \implies \frac94`

Finally, convert the improper fraction into a mixed number:

`\sf \implies 2 \frac14 \ cups`
