Set up proportion equation: Set up the proportion as an equation.We have the proportion 98=p12. To solve for p, we need to find the value that makes this equation true.
Cross-multiply to eliminate fractions: Cross-multiply to eliminate the fractions.Cross-multiplying gives us 8×p=9×12. This step is based on the property that if ba=dc, then a×d=b×c.
Perform multiplication on both sides: Perform the multiplication on both sides. 8×p=108 (since 9×12=108).
Divide to solve for p: Divide both sides by 8 to solve for p.p=8108.
Calculate value of p: Calculate the value of p.p=13.5 (since 108÷8=13.5).
