Answer:
a) 3.6 minutes
b) 0.01
c) 356.4
d) 0.99
Step-by-step explanation:
a) What number of minutes corresponds to 1% of the total of minutes you have to work tomorrow?
We can use a rule of three and solve for x:
360 minutes ------ 100%
x minutes ---------- 1%
x= 360/100 = 3.6 minutes
b) To find the number in part (a), we can multiply 360 by what number?
We can multiply by 0.01 which is the decimal expression of 1%
x= 360 x 0.01 = 3.60.
c) If you have worked 1% of the total 360 minutes, what percent of the 360 minutes do you have left to work?
We can use a rule of three and solve for x again:
360 minutes ------ 100%
x minutes ------------ 99%
x= 360(99)/100 = 356.4 minutes.
d) To find the answer in part (c), we can multiply 360 by what number?
Since we need to know how many minutes are the 99% of the work that we have left, we can multiply by .99 which is the decimal expression of 99%
x= 360 (.99) = 356.4 minutes.
