Lincoln Middle School had a canned food drive. The 6th graders brought in 5.75 boxes of canned food, the 7th graders brought in 6.5 boxes of canned food, and the 8th graders brought in 7/1.3 boxes of canned food. What was the total number of boxes of canned food brought in by the three grades?

The total number of boxes of canned food brought in by the three grades is 17.63 boxes

Step-by-step explanation:

To find the total number of canned foods brought in by the three grades, we will have to add the number of canned foods brought by each of the grades to each other. Careful attention has to be paid to the decimal points.

Canned foods brought by 6th graders: 5.75 boxes

Canned foods brought by 7th graders: 6.5 boxes

Canned foods brought by 6th graders: 7/1.3 boxes

We may have a slight challenge adding in 7/1.3 boxes to the other figures. What we can do now is to evaluate it to a decimal value by dividing it up.

7/ 1.3 will be the same thing as 7 divided by 1.3 = 5.38 boxes.

hence, we have 5.75 +6.5+ 5.38= 17.63 boxes

The total number of boxes of canned food brought in by the three grades is 17.63 boxes
