| Question | Answer |
|---|---|
| A fraction to a percent: | Multiply the fraction by 100 and reduce it. Then, attach a percent sign. |
| A decimal to a fraction: | Starting from the decimal point, count the decimal places. If there is one decimal place, put the number over 10 and reduce. If there are two places, put the number over 100 and reduce. If there are three places, put it over 1000 and reduce, and so on. |
| A decimal to a percent: | Move the decimal point two places to the right. Then, attach a percent sign. |
| A percent to a decimal: | Move the decimal point two places to the left. Then, drop the percent sign. |
| A percent to a fraction: | Put the number over 100 and reduce. Then, drop the percent sign. |
| Finding Area | Square A = a2, in which a is one of the sides. |
| Finding Area Rectangle | A = ab, in which a is the base and b is the length |
| Finding Area Parallelogram | A = bh, in which b is the base and h is the height. |
| Finding Area Circle | A = πr2, in which π is 3.1416 and r is the radius. |
| Finding AreaEllipse | A = πr1r2, in which π is 3.1416, r1 is the longer radius, and r2 is the shorter radius |
| Finding AreaTrapezoid | A = (h[b1 + b2])/2, in which h is the height, b1 is the longer parallel side, and b2 is the shorter parallel side. |
| Finding AreaTriangle | Given base and height: A = (1/2)bh, in which b is the base and h is the height. Given side, angle, side (SAS): (1/2) ab x sinθ, in which a is one side, b is another side, and θ is the known angle. Given three sides: when s = (a + b + c |
