Answer:
3.5% of 20, (0.035)*20, and 7% of 10
Step-by-step explanation:
Converting the mixed number (3 1/2) to a decimal yields 3.5, so 3.5% of 20 is correct.
3 1/2 is not equal to 3 1/2%, so 3 1/2 * 20 is not correct.
Converting the percentage to a decimal yields .035 which makes .35 too large, so (0.35) * 20 is not correct.
Changing the percentage to a decimal yields .035, so (0.035) * 20 is correct.
If you divide 20 by 2, you get 10, and if you multiply 2 by 3 1/2, you get 7. The 2 remains part of the expression, so it is equal to 3 1/2 of 20.
