Answer:
75% (75.45%)
Explanation:
I'm assuming Buddy's total calories are 2000 calories a day. The problem wants you to find what percentage of 2000 is 1509. You can do this by dividing 1509 by 2000.
1509 / 2000 = 0.7545
Make this number a percent by moving the decimal place to the right twice.
75.45
Buddy ate 75.45% of his total calories (or 75% if you round to nearest whole number).
