Thank you for participating in my school science project. I am trying to see if listening to different types of music will affect how well students do when taking a test.
You will have 10 minutes to take this quiz. There will be no music playing during this quiz to use as a comparison. Please be sure to type your answers as numbers only.

### 6805 - 1945 =

Explanation
The correct answer is 4860. The subtraction problem involves subtracting 1945 from 6805. When subtracting, we start with the ones place and subtract 5 from 5, which equals 0. Moving to the tens place, we have 0 minus 4, which requires borrowing from the hundreds place. The hundreds place becomes 7 minus 1, which equals 6. Finally, in the thousands place, we have 6 minus 9, which requires borrowing from the ten thousands place. The ten thousands place becomes 6 minus 1, which equals 5. Therefore, the result is 4860. The additional answer, 4,860, is just the same number written with a comma for readability.

### Students in my class are working on 20 projects for the science fair.  One fifth of the projects are about plants. How many are about plants?

Explanation
One fifth of the total projects means that the projects about plants make up 1/5 of the total number of projects. So, if there are 20 projects in total, 1/5 of 20 is equal to 4. Therefore, there are 4 projects about plants.

Rate this question:

• 12.

### 2/7 + 3/7 =

Explanation
The given question asks to add the fractions 2/7 and 3/7. When we add these fractions, the numerator (2 + 3) remains the same and the denominator (7) also remains the same. Therefore, the sum of 2/7 and 3/7 is 5/7.
