Question

Evaluate 1/4xy if x=−2/3 and y=3/5 . Write your answer as a fraction in simplest form.

Answer 1

(-1/10)

Explanation:

I'll assume 1/4xy is (1/4)xy and not 1/(4xy).

(1/4)xy

(1/4)(-2/3)(3/5)

Multiple the numerators and denominators separately:

Numerator + 1*(-2)*3 = -6

Deniominator 4*3*5 = 60

Put them back together: (-6/60) This reduces to (-1/10)
