Therefore the numerator must have a factor of 7 in it so that the simplified fraction has a denominataor that has a prime factorization of only 2ʹs and 5ʹs. Therefore x can be any multiple of 7 that is less than 3500. 28) 100 grid represents 900 l column represents 90 1 small square represents 9 Therefore 225 is 2 columns and 5 squares 2(90) + 5(9) =180 + 45 2 columns and 5 small square is 25% of the grid. Thus the answer is 25%. 39 50 4 30) 0.428571 31) 14 stops 32) 2 3 33) 4 34) $20,720 35) $613 36) 32% 37) 60% 38) $7200 39) Answers will vary.
