Method I Comparing the two sides of equation, 3.14 and 17.5 are at both sides of the equation so you can equate the ones which are not the same. 3p=18 Divide both sides by 3 p=
18
3
=6 Method II (3.14×18)×17.5=3.14×(3p×17.5) The above equation is the same as 3.14×18×17.5=3.14×3×p×17.5 You can solve for the value of p by dividing both sides of the equation by 3.14×3×17.5 p=
3.14×18×17.5
3.14×3×17.5
p=6.0 Note: 3.14 and 17.5 cancel each other and 3 divides itself once and 18,6 times.
