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.

He is charged an additional $0.55 for each mile driven over 1,000. If x represents the total mileage Jack drives each month, and if he always drives over 1,000 miles per month, what expression can be used to calculate his total monthly car rental bill. - correct answer -his rental fee will include the $200 plus 0.55 x the number of miles he drives over 1,000 miles. if x= total miles, then x-1000 = the total miles driven over 1,000. therefore t
