We already know that the hourly rate for John is : 1/6 and the hourly rate for Rick is : 1/8. What we don`t know is a hourly rate for Molly and we will call it 1 / x.
The hourly rate for all together is: 1 / 3
An equation is:
1 / 3 = 1 / x + 1 / 6 + 1 / 8
1 / 3 = 1 / x + 4 / 24 + 3 / 24
1 / 3 = 1 / x + 7 / 24
1 / x = 1 / 3 - 7 / 24
1 / x = 8 / 24 - 7 / 24
1 / x = 1 / 24
1 / 3 = 1 / 24 + 1 / 6 + 1 / 8
The hourly rate for Molly is 1 / 24. Molly can paint the room alone for 24 hours.
X = 18.8 bc that’s the only thing that makes sense and us lazy people don’t need to work things out
53 because it is the last one all the others have 54
Answer: Yes because the quotient of the fraction 2 over 3 divided by fraction 1 and 3 over 4 is 2 and 5 over 8
Step-by-step explanation: To make to scarves would take 4/3 yards of fabric. If she has 1 and 3/4 yards then that means she has 7/4 yards. If we change them to have the same denominator of 12 Jessica has 21/12 yards and she needs 16/12 yards. So yes she has enough. Then we know that there is enough for two so the fraction of how much she it takes to make one scarf should be divided by how much she has to equal a little over two.
