Alec needs 432 inches of molding to put along the ceiling of his dining room. How many yards of molding should he buy. - correct answer -this is a straight conversion problem. there are 36 inches in 1 yard. converting from a smaller unit to a larger unit requires division: 432/36=12. John, Mike, and Dillion are painting a fence. John paints 1/4 of the fence and Mike paints 2/5th of the fence. How much of the fence is left to paint for Dillion - correct answer -The correct answer is 7/20. rewrite all fractions with a common denominator. lowest common denominator for 1/4 and 2/5 is 20: 1/4 x 5/5 = 5/20, and 2/5 x 4/4 = 8.20. these fractions represent how much of the fence has been painted. so, 5/20 + 8/20 = 13/20 of the fence has been painted. Therefore 1 - 13/20 = 20/20 - 13/20 = 7/20 The Andersons went out to dinner Saturday night and had a bill of $190.00.
