On average it takes Miguel 45 minutes to compete his math assignments and 30 minutes to complete his science assignments. If he had 24 math assignments this grading period , what was his total minutes spent on math ?

24 * 45 = _______ minutes

To find the total minutes Miguel spent on math assignments, we need to multiply the average time it takes him to complete one math assignment by the number of math assignments he had.

The average time it takes Miguel to complete one math assignment is 45 minutes. We multiply this by the number of math assignments he had, which is 24.

Total minutes spent on math = Average time per math assignment * Number of math assignments
Total minutes spent on math = 45 minutes * 24 math assignments

Now, let's calculate the total minutes spent on math:
Total minutes spent on math = 1080 minutes

Therefore, Miguel spent a total of 1080 minutes on math assignments this grading period.
