(p-3)/7p = 5/12 Cross Multiply: 12(p-3) = 7p(5) Distribute: 12p-36 = 35p subtract 12p from each side: -36 = 23p divide each side by 23: p = -36/23
4 over 5. :P
YES!!! 5.454545.... is rational because it can be converted to a ratio/fraction. Let P = 5.454545.... 100P = 545.454545.... Subtract 99P = 540 )Note the repeating decimals subtract to zero.). P = 540/99 P = 60 / 11 P = 5 5/11 Done!!!!
4 with a remainder of 4
PQR P=2 Q=4 R=5 2 x 4 x 5 = 40
