The total amount of concrete poured is ? cubic yards.

Question

A construction crew pours 12 and three fourths cubic yards of concrete on Monday and 14 and one half cubic yards of concrete on Tuesday. The total amount of concrete poured is? cubic yards.

Answer 1

Add the mixed numbers.

 

12 3/4 + 14 1/2

 

14 1/2 is equivalent to 14 2/4

 

12 + 14 = 26, and 3/4 + 2/4 = 5/4 = 1 1/4

 

So, 26 + 1 1/4 = 27 1/4 yd³

 

You could have also converted each mixed number to an improper fraction, found the LCD (least common denominator), and then add the two fractions
