Ratios are basically a number v a number. Like if your in a group of 30 people and 10 of them are boys, your ratio of girls to boys would be 20:10. That's like really really basic ratio and idk how advanced in rations you are but yeah.

Answer:

Suppose you are in a cinema and there are 12 men and 36 women, then the ratio men to women is 12:36, dividing each term by 12 we get 1:3, which is an equivalent ratio. Other way to get an equivalent ratio is multiplying each term by some constant, for example if we multiply each term in the ratio 1:3 by 4 we get the equivalent ratio: 4:12.

Ratios are used to show the relative sizes of two values, in the example, the relative amount of men and women in some place.

-4/5 to the power of 2 times -3/50

Crazy boy [7]

=(-4/5)^2 * -3/50
square -4/5 first; remember -4/5^2 is the same as -4/5 * -4/5

=(-4/5 * -4/5) * -3/50
multiply -4 numerators; multiply 5 denominators

=(-4 * -4)/(5 * 5) * -3/50

=16/25 * -3/50
multiply numerators 16 & -3; multiply denominators 25 & 50

=(16 * -3)/(25 * 50)
= -48/1250

simplify by 2
= -24/625 (or -0.0384)

ANSWER: -24/625 (or -0.0384)

Hope this helps! :)
