Question

ventura coal mined six and two third tons on Monday and seven and three fourth on Tuesday, and four and one half tons on Wednesday. if the goal is to mine 25 tons this week, how many more must be mined

Answer 1

6 1/12 tons

Explanation:

A calculator can tell you the remaining amount:

25 - (6 2/3) - (7 3/4) - (4 1/2)

= 25 -6 -7 -4 -(2/3 +3/4 +1/2)

= 8 - (8/12 +9/12 +6/12) = 8 - 23/12

= 6 1/12 . . . . tons
