Please check my answer to see if I got it right. Thanks.
Braden has 1 hour of math homework to do. He spends 2/5 of this time complaining about how much he hates math, 1/3 of the total time looking for his calculator. How much time does Braden actually work on his math homework?
My answer:
1 hour = 60 min
2/5 x 60/1 = 120/5 = 24
60-24 = 36
1/3 x 36/1 = 36/3 = 12
36-12 = 24
He spends 24 min working on his math homework.
Am I right? If not can u pleese help me :)
Right!
Thank you :D
You're welcome.
Your calculations are correct, but your final answer is not correct. Let's go through the steps again to see where the mistake occurred.
You correctly converted 1 hour to 60 minutes. Then you calculated that Braden spends 2/5 of this time complaining about math, which is 24 minutes. You subtracted this from the total time, which gave you 36 minutes remaining.
Next, you calculated that Braden spends 1/3 of the total time looking for his calculator, which is 12 minutes. However, instead of subtracting this from the remaining time (36 minutes), you subtracted it from the original total time of 60 minutes, which gave you 24 minutes.
To find the actual time Braden works on his math homework, you need to subtract the time spent complaining and looking for the calculator from the total time of 60 minutes. Let's correct that:
36 minutes - 12 minutes = 24 minutes.
Braden actually works on his math homework for 24 minutes, which is the correct answer. Good job on the calculations, just a small error in subtracting the time spent looking for the calculator.
