We will first translate this word problem into numerical expression.
Twelve and three tenths more than five and thirteen thousandths of a number d is equal to fifteen and three hundred two thousandths can be written into this form;
5.013d + 12.3 = 15.302
We can now solve for d,
Add -12.3 to both sides of the equation
5.013d + 12.3 - 12.3 = 15.302 - 12.3
5.013d = 3.002
Then, divide both side of the equation with 5.013
5.013d / 5.013 = 3.002 / 5.013
d = 0.60
Therefore, the value of d is 60 hundredths or 0.60.
