## ahoward79 2 years ago Raoul prints a poster using an aspect ratio of 4 over 5. Which of the following aspect ratios could Raoul also use without distorting the picture? 1 over 4 5 over 6 8 over 10 8 over 9

The third one.

3. calculusxy

You have to multiply both 4 and 5 by 2.

4. ahoward79

Which equation represents a true proportion? 3 over 4 = 9 over 12 3 over 4 = 9 over 16 5 over 8 = 9 over 12 5 over 8 = 9 over 16

5. xoya

Yes he's right :)

6. calculusxy

@ahoward79 The first one.

7. xoya

3 over 4 = 9 over 12

8. xoya

Yes :) multiply both 3 and 4 by 3 :)

9. calculusxy

Multiply the 3 and 9 by 3 and you get 9 and 12. :)

10. calculusxy
