Answer:
Ed used 39/60 of one hour to complete his tasks.
Step-by-step explanation:
Find the least common denominator (LCD), which would be 20
Then, find how to get from 5 to 20 and 4 to 20.
Use division.
20/5 = 4, 20/4 = 5
After this, multiply the numerator to the according number.
2*4 = 8 = 8/20
1*5 = 5 = 5/20
Make the denominator 60 to represent 60 minutes in one hour
5/20*3/3 = 15/60
8/20*3/3 = 24/60
Add the two results.
15/60 + 24/60 = 39/60
Well if you divide 25.6 by 8 and then multiply four by that answer then you have the answer for a, so 4 times 3.2=12.8 , and then you would multiply 25.6 and 12.8 which is 327.68
(1+1)x+1 and 4x+10
