Paolo helped in the community garden for 243 hours this week. That was 165 equal-length shifts, because Paolo stopped early one day when it started to rain.How long is a single shift? hours
Q. Paolo helped in the community garden for 243 hours this week. That was 165 equal-length shifts, because Paolo stopped early one day when it started to rain.How long is a single shift? hours
Convert to Improper Fractions: Convert the mixed numbers to improper fractions to make the calculations easier.2(43) hours can be converted to an improper fraction by multiplying the whole number by the denominator of the fraction, adding the numerator, and then placing the result over the original denominator.2(43)=(2×4+3)/4=(8+3)/4=411 hours.1(65) shifts can be converted in the same way.1(65)=(1×6+5)/6=(6+5)/6=611 shifts.
Calculate Total Time Worked: To find the length of a single shift, divide the total hours worked by the number of shifts.We have 411 hours for the total time worked and 611 shifts.(411)÷(611)=(411)×(116)=4×1111×6.
Simplify Expression: Simplify the expression by canceling out the common factors.The number 11 in the numerator and denominator cancels out, as does one factor of 2 in the 6 and 4.This leaves us with 46 after canceling out 11, and then we simplify 46 by dividing both the numerator and the denominator by 2.46=(4/2)(6/2)=23.
Convert Back to Mixed Number: Convert the improper fraction back to a mixed number if necessary.23 hours is the same as 121 hours or 1.5 hours.So, a single shift is 121 hours long.
