What percent of 1,000 is 150?
%28x%2F100%291000+=+150…….cancel two zeros in 100 and 1000
x%2A10+=+150…divide both sides by 10
x+=+15%

46 is 20% of what number?
%2820%2F100%29x+=+46…….on left side 20%2F100 divide both numbers by 20 and you will have 1%2F5
%281%2F5%29x+=+46…….multiply both sides by 5
%281%2F5%2A5%29x+=+46%2A5

x+=+230

What is 0.8% of 1,778
%288%2F100%291778+=+x…….divide 8 and 100 by 4
%282%2F25%291778+=+x……
0.08%2A+1778+=+x
x+=++142.24

If there are 470 students in the class and 40% of the class are males, how many males are in the class?

0.4%2A470+=+x…….
x+=+188…………. There are 188+males in the class
During a sale, a television that usually sells for $900 is on sale for $ 765. What is the percent decrease in price?
%28x%2F100%29900+=765…….

x%2A9+=765…….
x+=+85%
Then decrease is 100+%96+85=+15%
