With a ratio of 5/11, that 5" will be adequate.
5/11 = 5/x
However, for the 4":
5/11 = 4/x
Multiply both sides by 11x and divide by5.
x = 4(11/5) = 8.8
My son is struggling with ratios and Ploygons. The word problem is:
Lydia wants to use a photocopier to increase the size of a small chart. The chart is 4 in. by 5 in. If she uses a scale factor of 5:11 will the chart fit on a 8 1/2 x 11 sheet of paper? Can some explain to me how to factor this so I can help him with his other problems?
Thank you in advance
