RATIOS & PROPORTIONS
A ratio is a comparison of two quantities. Ratios can be written several ways. A ratio of 7 to 6 may be written 7:6 or could be written 7/6. The word ratio is pronounced "rash – e – o" with a "long a" in "rash".
A very useful problem solving technique is to learn how to write a proportion for information given in a problem. This is called solving problems using the ratios and proportions.
ESTIMATE REASONABLE SOLUTIONS WITH FRACTIONS AND DECIMALS
We'll now switch gears a little and look at working with fractions and decimals. Often times all that we need is an estimate of the actual amount. We will use rounding to nearest 1/2 for fractions and nearest 0.5 for decimals to estimate a reasonable solution.
