Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .

Answers

Answer 1

Answer:

A. Ruby added instead of divided

Step-by-step explanation:

You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer

12/15 times 15/2 equals 180/30 which, when simplified equals 6

Answer 2

Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

What is simplification?

Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15

Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Step-by-step explanation:

6x10=60    150-60=90

Answer:

0.4 or 2/5???

Step-by-step explanation:

I believe this is a proportion/ratio problem.

Think of it like this:

x/6 = 10/150

To solve for x, you must cross multiply:

150x = 6*10 (150x... DON'T write 150*x, that is nonsense)

150x = 60

     x = 60/150  (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)

     x = 6/15

     x = 2/5 or 0.4  (I simplified it)

Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4

Find the rate of change from 2012 to 2016

A. -10.5 students per year
B. 10.5 students per year
C. -11.25 students per year
D. 11.25 students per year

Answers

Answer:

D. 11.25 students per year

Step-by-step explanation:

rate of change

[tex] = \frac{400 - 355}{2016 - 2012} [/tex]

[tex] = \frac{45}{4} [/tex]

=11.25

The rate of change from 2012 to 2016 is 11.25 students per year.

Therefore, the correct answer is D.

Given that a graph is showing the number of students in a class.

We need to find the rate of change from 2012 to 2016.

Also, from the graph we can see the number of students in 2012 and 2016 was 355 and 400 respectively.

To find the rate of change from 2012 to 2016, we can use the formula:

Rate of change = (Final value - Initial value) / Time interval

In this case, the initial value is the number of students in 2012, which is 355, and the final value is the number of students in 2016, which is 400.

The time interval is 4 years (from 2012 to 2016).

Plugging these values into the formula, we get:

Rate of change = (400 - 355) / 4

= 45 / 4

= 11.25

Therefore, 11.25 students have changed between 2012 and 2016 with this rate of change.

Answer:

Step-by-step explanation:

We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.

g÷ 5/8 =1
basically its asking what divided by 5/8 = 1

Answers

Answer:

5/8 divided by 5/8 = 1

Step-by-step explanation:

First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.

[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]

Now, multiply both sides by 5 to get rid of the fraction.

[tex]8g = 5[/tex]

divide both sides by 8

[tex]g = 5/8[/tex]

It’s asking you to what 5/8= 1 to do basically you have to multiply the 8 to both sides and then you probably will get your answer but I’m not to sure
