The answer is usually written as "10x".
by multipling
8 x 21 = 168
1/x = 2/6 and by cross multipling 2x = 6 so x =2
There are infinitely many answers. Two possibilities are 10*31.5 and -1 * -315
You add as many zeros to the number as you have in the power of 10.
80/x = 8/20 Taking reciprocals of both sides, x/80 = 20/8 Multipling both sides by 80, x = 80*20/8 simplifying: x = 20*80/8 = 20*10 = 200.
25x2
1/4 x 1/4 = 1/16 1/3 x 1/2 = 1/6 1/16 x 1/2 = 1/32
The product is the answer to a mulitplication problem.
