350 is 40% of what number?

Explanation:
Understanding percents: if a value is a certain percent of a number, you set up 0.40 × N = 350 and solve for N. Dividing both sides by 0.40 gives N = 350 ÷ 0.40 = 875. You can also use 40% = 2/5, so (2/5)N = 350, hence N = 350 × (5/2) = 875. Therefore the number is 875, since 40% of 875 equals 350. For reference, 700 would give 280 as 40%, and 350 would give 140, so those don’t fit.
