Answer:
1/5
1/3
Step-by-step explanation:
For the first problem:
5/7 of ... is 1/7
so
5/7 of x is equal to 1/7
so
(5/7)x = (1/7)
so
x = (1/7)/(5/7)
so
x = 1/5
For the second problem:
5/7 of ... is 5/21
so
5/7 of x is equal to 5/21
so
(5/7)x = (5/21)
so
x = (5/21)/(5/7)
so
x = 1/3

Answer:
it would take 65 hours to produce all of the order.
Step-by-step explanation:
1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.
2. You would figure out that 26+26 is 52 so 52 hours for 8 cases
3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?
4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.
5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.
6. finally you multiply 26+26+13 which you would get 65 as the answer
