Question

Angie completes 80% of her homework problems before basketball practice. She was assigned 30 problems total. How many problems were completed before basketball practice?

23
24
25
26

Answer 1

24 problems

Explanation:

I like to do it like this: I find out what 10 percent is, so I divide it by 10. 30/10=3. 10 percent plus 10 percent is 20 percent. That's 6. 100 percent minus 20 is 80 percent. 30 - 6 is 24. Hope this helps.

Answer 2

24 questions

Explanation:

you would make the percentage a decimal and times that by how many problems.
