Question

Marco ordered a set of beads. He received 4,000 beads in all. 2,080 of the beads were red. What percentage of the beads were red?

Answer 1

When you see a problem that uses the words "percent" and "of," you can solve it with (part / whole) • 100.

In this case, the part is the number of red beads (2080) and the whole is the total number of beads (4000), so the equation you would write is (2080 / 4000) • 100 = 52%.
