While there are striking similarities across countries regarding the ideals that men are expected to adhere to (Gilmore,1990), the extent to which men have to conform to such norms differs across societies (Traister,2000). This raises the question: Where do masculinity norms come from? The ori...
Equivalent ratios are fractions that are derived from each other so that their values are equal. They can be considered as ratios that compare with each other such that one ratio is equal in value to the other ratio. The ratios are considered to be equivalent because the numerator and denomin...
There are a number of strategies that can be used in the process to solve ratios, proportions, and rates. If it is known that the ratios or rates are proportional the two ratios are equivalent. Put both into fraction form, equal to each other. Then, solve for the missing value using th...

Thus, in geometrical proportion, the first term to the third is said to be in a duplicate ratio of the first to the second, or as its square is to the square of the second. Thus, in 2, 4, 8, 16, the ratio of 2 to 8 is a duplicate of that of 2 to 4, or as the square...
