Lenox ironed 1/4 of the shirts over the weekend. she plans to split the remainder of the work eqaully over the next 5 evenings?
a. what fraction of the shirts will lenox iron each day after school? If Lenox has 40 shirts, how many shirts will she need to iron on Thursday and Friday?
There is 75% of shirts left to do, split over 5 days, you can divide 75 by 5 to get 15% each day.
As a fraction you need 3/4 to be done over 5/1 days
divide 3/4 divided by 5/1
copy, change, flip
3/4 x 1/5
3x1=3 4x5=20 that's 3/20 if you divided that into a percentage its also 15% so you know you're right.
For part 2, that's simple because you can decide if 40 shirts includes the 1/4 you already did. In that case find out what 40/4 is. That's 10. If you did 10, you need to do 30 more. That would mean that 30/5 because there is 5 days. 30/5 is 6. 6 would be for 1 day, you need to know 2. That's 12.
If 40 does not include the 1/4 you already did, and it's 40 remaining. You'd have to do 40/5 which is 8. Then 8x2 is 16.
But I think the other person is correct, it would be 40 total so it should be 12 shirts.
A. If she completed 1/4, 3/4 are still left to be done over 5 days. To find out how much per day, divide 3/4 by 5 (multiply the first number by the reciprocal of the second). 3/4*1/5= 3/20.
Final answer: 3/20
b. If she irons 3/20 a day, she should iron 6/20 or 3/10 over the course of two days, Thursday and Friday. 3/10 of 40 is 40*0.3= 12
Answer: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
