Since addition is commutative and associative, we can add the numbers in any order we wish. Let's add the whole numbers together and the fractions together. 4++3+=4+3++ 4+3++=7+5+=7+ Next we can re-write as a mixed number... 7+=7+=7++=7+1+ and add the whole numbers once again. 7+1+=8+ =, 8. 8 Since we can write the sum as So we see that this recipe makes gallons of punch.
