Final answer:
To solve for p in the equation 6(p+2.25)=15 9/10, first convert 15 9/10 to a decimal to get 15.9. Then divide both sides by 6 and subtract 2.25 to find that p equals 0.4.
Step-by-step explanation:
To solve for p, we start with the equation 6(p+2.25)=15 9/10. First, convert 15 9/10 to an improper fraction or a decimal to make the equation easier to work with. In decimal form, 15 9/10 is 15.9. Then we can solve the equation as follows:
Divide both sides by 6 to isolate the (p+2.25) term. 15.9 / 6 = 2.65
Subtract 2.25 from both sides to solve for p. 2.65 - 2.25 = 0.4
Therefore, the solution for p is 0.4.
