Question

4. Suppose a copy machine is set to reduce a picture that's 8.5 inches by 11 inches to picture dimensions one-half the original size. What proportion shows this reduction? A. 8.5⁄11 = 5.5⁄4.25 B. 8.5⁄11 = 17⁄22 C. 8.5⁄11 = 2.125⁄2.75 D. 8.5⁄11 = 4.25⁄5.5

Answer 1

B. because so what u need to do is.....

8.5÷11=  0.77272... so then you try the other side which is

17÷22= 0.77272... and so your answer will be

                                         B. 8.5/11 = 17/22

Answer 2

so the 8.5/11 will be reduced by half.

half of 8.5 is 4.25.

half of 11 is 5.5............................$\bf \stackrel{original}{\cfrac{8.5}{11}}=\stackrel{reduction}{\cfrac{4.25}{5.5}}$
