.5 as a decimal and 50% as a percent
306/6 is 51 is you add one to one side and take away the other the six numbers become: 46, 48, 50, 52, 54, 56 as you added one to one side substituting the other you took away from, therefore the smallest would be 46.
Y=5/2x+5 because the slope is 5/2 and the y-intercept is 5
