Today on Math Out Loud we’ll be comparing and contrasting ratio and proportion, R-A-T-I-O and P-R-O-P-O-R-T-I-O-N. A ratio is a comparison of two quantities with a colon, a fraction or the word to. With ratios, order matters! Ratios are used in a proportion when looking for a prediction. A proportion is the fraction that solves which has two equivalent ratios. A proportion is used to find the prediction that is found by multiplying. They are both different because the ratio is a comparison and a proportion is an equation that compares two ratios. They are similar because they are both used to find a prediction. They are also similar because they compare ratios. We are the Math Masters with the word comparison of ratio and proportion on Math Out Loud.
