Answer:
b = 5/12
Step-by-step explanation:
You have the proportion
1/(3b) = 4/5
Cross multiply to get rid of the fractions...
5 = 12b now solve for b
5/12 = b (divide by 12 on both sides)
Complex numbers are numbers that can be expressed in the form a + bi, a and b are real numbers whereas I is the imaginary unit that satisfies the equation I^= -1. In this expression, a is referred as the real part of the complex number, b is referred as the imaginary part.
