How to Using Decimals, Grid Models, and Fractions to Represent Percent
- Solve the equation: part = (decimal) * whole => x = 0.25 * 50 => x = 12.5
- Check your work: $50 – $12.5 = $37.5, which is the price of the shirt after a 25% discount.
- The sale price of the shirt is $37.5 or 25/100 of the original price.

Using Decimals, Grid Models, and Fractions to Represent Percent – Examples 3
Shade 72 of the 100 squares to represent 72% of the grid model.
As a fraction, 72% is equivalent to \(\frac{72}{100}\).
As a decimal, \(72÷100=0.72\)
Divide the numerator and denominator by 4 to write the in the simplest form.
\(\frac{72}{100}=\frac{72÷4}{100÷4}=\frac{18}{25}\)
Original price was: $109.99.$54.99Current price is: $54.99.
Original price was: $109.99.$54.99Current price is: $54.99.
