Answer

a.) Greater b.) Less c.) Less

Work Step by Step

a.) The ratio of minutes to seconds is $1:60$. To find the number of seconds in a minute, multiply the number of minutes by 60. Because you are multiplying the minutes by 60 to find the number of seconds, the number of seconds is greater than the number of minutes. b.) The ratio of centimeters to inches is $1:0.3937$. To find the number of inches in $x$ centimeters, you need to divide the number of centimeters by 0.3937. Because you are dividing the number of centimeters by the conversion rate, the number of inches is less than the number of centimeters. c.) The ratio of kilometers to miles is $1:0.621371.$ To find the number of miles in a kilometer, you need to divide the number of kilometers by 0.621371. Because you are dividing the number of kilometers by the conversion rate, the number of miles will be less than the number of kilometers.
