As you know .5 is the same as half of the number, you can first solve for 1/2 of .576
To do this, divide 76 by 2 and 500 by 2.
76/2=38 and 500/2=250
38+250=288
Now put back in the dicimal point. .288
So now that we know that .5 of .576, we need to divide it by 10 so that we have .05 of .576. All we have to do is move the point one spot over to the left.
The answer is 0.0288.
