Find a percent of a quantity and interpret the result in context.

Screen for correct percent-of-quantity representations

Problem

Evaluate every representation below as a model of \(17.5\%~\text{of}~80\).

Representations to check:
1. \(0.175~\times~80~=~14\)
2. \(10\%~\text{of}~80\) plus \(7.5\%~\text{of}~80\) equals \(14\)
3. \(14\) is \(17.5\%\) more than \(80\)
4. A water tank holds \(80~\text{liters}\), and \(14~\text{liters}\) is \(17.5\%\) of the tank
5. \(17.5/100~\times~80~=~140\)
6. \(7/40~\text{of}~80~=~14\)

Include every representation that is correct.
