370 papers need gradeed only 80% of them get done. How many ungraded papers will remain to be completed?

- Definitely not "college" -- arithmetic? -

Please type your __subject__ in the **School Subject** box. Any other words, __including obscure abbreviations__, are likely to delay responses from a teacher who knows that subject well.

multiply 370 by 0.8 (80% = 0.8)

subtract that result from 370

What do you get?

- college -

a quicker way to do is multiplying 370 by .20 (20% of the paper needed not to be graded)
