To find the percent of a number, just turn the percentage into a decimal. To do that just go 2 decimal places to the left. For example, 25% becomes 0.25. Then, just multiply that decimal by the number you're finding the percentage of. That's it!

Ex. Find 50% of 10

50% becomes 0.5
0.5(10)= 5

50% of 10 is 5.

ICE Princess25 [194]
If 4 is 100-84=16 % of his workout, 4 is 16/100 or 4/25 of his workout.  If 4=4x/25, where x is his workout length, dividing by 4 and multiplying by 25 gives x=25, so Dave must run 25 laps total.

Andy is solving a quadratic equation using completing the square. If a step in the process results in = (x – 6)2, could the orig
Zarrin [17]
<span>Yes, the equation can be solved by factoring. Using the given equation, take the square root of both sides. Both 169 and 9 are perfect squares, so the left side becomes plus or minus 13/3, which is rational. Six plus 13/3 is a rational number, and 6 minus 13/3 is also a rational number. If the solutions of a quadratic equation are rational, then the equation is factorable. </span>
