Order negative rational numbers from least to greatest -3.75,-0.55,-3%,-1/2,-1/5

its 4 because 2 times 2 is 4, if you double the number two you get four

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

x = 3 ± √(5+y)
