can someone please tell me the answer to these 2 questions for my study guide??
7.find the quotient
5/20 divided by 1/7=
A.1 1/4
B.4/5
C.5/196
D.4/21
9.Michael spends 3 hours cleaning his house,he spends equal amounts of time cleaning each room.If he spends 1 hour cleaning each room,how many rooms does his house have?
A.2 rooms
B.3 rooms
C.5 rooms
D.6 rooms
(5/20) / (1/7)
(5/20) * (7/1) = 35/20 = 1 15/20 = 1 3/4
As Reiny told you, the answer is not given. Check for typos or report this error to your teacher.
9.
3 hours total
1 hour per room
He must have 3 rooms -- as Reiny indicated.
oh im sorry I realized I did have a typo in the first one
Sure, I can help you find the answers to these questions and explain the process to you.
Let's start with question 7. To find the quotient of 5/20 divided by 1/7, you need to follow these steps:
1. Invert the second fraction (divisor): 1/7 becomes 7/1.
2. Multiply the first fraction (dividend) by the inverted second fraction: (5/20) * (7/1).
3. Simplify the result if possible: (5 * 7) / (20 * 1) = 35/20.
Now, let's simplify the fraction 35/20 to its simplest form:
1. Find the greatest common divisor (GCD) of the numerator (35) and the denominator (20). In this case, the GCD is 5.
2. Divide both the numerator and the denominator by the GCD: (35/5)/(20/5) = 7/4.
So, the quotient of 5/20 divided by 1/7 is 7/4, which corresponds to option A.1 1/4.
Moving on to question 9. We know that Michael spends 3 hours cleaning his house, and he spends an equal amount of time cleaning each room. If he spends 1 hour cleaning each room, we need to determine how many rooms his house has.
To find the number of rooms, you can divide the total time by the time spent cleaning each room:
1. Divide the total time (3 hours) by the time spent cleaning each room (1 hour): 3/1 = 3.
Therefore, based on the information provided, Michael's house has 3 rooms, which corresponds to option B.3 rooms.
I hope this explanation helps you understand how to find the answers to these questions. Let me know if you have any further inquiries.
