B is the answer how you do good
The lengths of the rectangles are 7 and 12 respectively. Form the ratio 7/12. The widths of the rects. are x and 5 respectively. Form the ratio x/5. Now equate these two ratios:
7 x
--- = ---
12 5
Solve this for x. One way to do this would be to cross-multiply, obtaining 12x = 35, and solving this result for x. x will be a fraction. Write the numerator and denominator in the boxes given.
The answer is the first choice, "5 and 6."
The square root of 35 is equal to 5.92, which is in between the numbers 5 and 6.
A six digit number that fits this criteria is 588588, for this number divided by 11 is a whole number, 53508. If you don't need to use both numbers, 555555 and 888888 also work as answers.
