Answer:
116 mg
Step-by-step explanation:
From the statement we have that a patient receives 1 1/3 mg of medicine per kilogram of his weight.
The first thing is to pass the mixed number 1 1/3 to a rational number, like this:
1 + 1/3 = 1.33
So it would be 1.33 mg of medicine per kg, if the patient weighs 87 kg, he should be given a total of:
1.33 * 87 = 116
A total of 116 mg should be given to that patient.
The LCD = 6x^2y^3 ( because LCD of 3 and 6 = 6, LCD of x^2 and x = x^2 and LCD of y and y^3 = y^3)
now divide 3x^2y into the LCD then multiply this by 5 to get the first term in the numerator and do similar process to get second term, so we get:-
5(2y^2) - 4(x)
------------------
6x^2y^3
= 2( 5y^2 - 2x)
-----------------
6x^2y^3
= 5y^2 - 2x
-----------
3x^2y^3
