Probably the simplest method is to cross-multiply. A/B = C/D is equivalent to A*D = B*C. The latter form is easier to check.
2.16=216/100=54/25 Whenever you want to convert a number to a fraction use this method: write it with no decimal point, and then split it by 1 followed by the number of «0»' s you want.
Oh, dude, you want to break down 5/8 into a sum of unit fractions? Easy peasy! It's just 1/2 + 1/8, like a math smoothie of fractions. So, 5/8 is basically 1/2 + 1/8. Math, man, it's like a puzzle that's already solved.
This is actually a question in my Digital Circuits text. Are they kidding? Is there a way to tell that a discrete decimal will have an endless binary equivalent?
Being one of the first to give a formula for solving quadratic equations is one contribution Sridhara Acharya made to mathematics. He also gave an exposition on zero, wrote practical applications of algebra separated algebra from arithmetic, and found the method of multiplying a fraction by the reciprocal of the divisor when dividing a fraction.
Oh, dude, the persistence method of forecasting is limited because it just blindly assumes that the future will be exactly like the past. Like, come on, life isn't a rerun of yesterday's sitcom. It's like trying to predict the weather by looking out the window and saying, "Yep, it's sunny now, so it'll be sunny forever." So yeah, it's limited because it doesn't account for any changes or surprises that might pop up.
The five common forecasting methods are executive judgement, surveys, time-series analysis, regression analysis and market tests. Market characteristics, purposes of the forecast, type of product and the costs involved are a few factors that the effect the choice of method for forecasting sales.

Currently, no earthquake forecasting method can predict the precise location of an earthquake. Earthquake forecasting typically provides estimates of the likelihood of earthquakes occurring in broad regions over specified time frames based on historical data and scientific models. The exact location and timing of earthquakes remain highly unpredictable.
Judgmental forecasting is the oldest and still the most important method of forecasting the future.
The very objective of business forecasting is to be accurate as possible, so that planning of resources can be done in a very economical manner and therefore, propagate optimum utilization of resources. Business forecasting helps in establishing relationship among many variables, which go into manufacturing of the product. Each forecast situation must be analyzed independently along with forecasting method.
One method of forecasting that predicts the arrival time of a storm based on its current speed and variables is extrapolation. This method involves using the storm's current direction and speed to estimate its position at a future time. By continuing this trend, meteorologists can forecast when the storm is expected to arrive at a particular location.
Cash flow projection is the most powerful tool in cash management. It enables companies to see the cash flowing in and out of an organization. The direct method of cash flow forecasting is to use the direct cash receipts and disbursements method.
A judgmental forecast is a forecasting method that relies on expert judgment and qualitative input rather than statistical models or historical data. It is based on the opinions and insights of individuals who have expertise in the subject matter being forecasted. This approach is often used when historical data is limited, unreliable, or unavailable.
There are many methods of sales forecasting. One method is to look at what has happened in the past and based on that, predict the future.
