Question

to start, shade 20% of the grid. click and drag to shade. write 20% as a decimal. 20% = write 20% as a fraction in simplest form. 20% = submit work it o not feeling ready yet? what percentage is illustrated? (100)

Explanation:

Step1: Convert percent to decimal

To convert a percentage to a decimal, divide by 100 (move the decimal point two places left).
$20\% = \frac{20}{100} = 0.2$

Step2: Convert percent to simplified fraction

First write the percentage as a fraction over 100, then simplify by dividing numerator and denominator by their greatest common divisor (20).
$20\% = \frac{20}{100} = \frac{20\div20}{100\div20} = \frac{1}{5}$

Step3: Calculate shaded grid cells

The grid has $10\times10=100$ cells. 20% of 100 is $0.2\times100=20$ cells, so 20 cells should be shaded.

Answer:

20 cells of the 100-cell grid should be shaded.
$20\% = 0.2$
$20\% = \frac{1}{5}$
