80% = 80/100 = .8 therefore 19 * .8 = 80% of 19 = 15.2,
10% is 1.9, so 1.9 + 1.9 + 1.9 + 1.9 + 1.9 + 1.9 + 1.9 + 1.9 = 80% of 19 = 15.2
To find 80 percent of 200, divide 80 by 100 and then multiply the answer by 200. In this case:(80 / 100) x 200 = 160
Set up a proportion. 50/80 = x/100 Multiply both sides by 100 x = 62.5%

Nitrogen makes up almost 80 percent of air. Oxygen makes up about 21 percent, with the remaining 1 percent made up of various gases such as carbon dioxide, argon, and others.
To find out what number 4 is 80 percent of, you can set up the equation: ( 4 = 0.8 \times x ), where ( x ) is the unknown number. To solve for ( x ), divide both sides by 0.8: ( x = \frac{4}{0.8} ). Calculating that gives ( x = 5 ). Therefore, 4 is 80 percent of 5.
