Find a ratio equivalent to 12/21 with lower terms

Here we are given the ratio 12 / 21.

In order to find its equivalent ratio with lower terms , we have to find common factor of 12 and 21 by which we can divide both the numbers.

So factors of 12 are 1, 2 ,3, 4.

Factors of 21 are 1, 3, 7.

So our common factor is 3 here.

dividing both numerator and denominator by 3 we have:

\frac{12/3}{21/3}

12 divided by 3 equals 4 and 21 divided by 3 equals 7.

So our new ratio becomes 4/7

Find factors of 12 and 21

Divide 3 from both numerator and denominator.

(12/21)/(3/3) = 4/7

4/7 is your ratio equivalent to 12/21

As the earth rotates, it travels a distance of 80 miles in 5 minutes. At this constant rate, which equation best represents y, t
solniwko [45]

Answer:

y=16x

Step-by-step explanation:

So, you are given the equation as if y=total distance the earth travels in x minutes. If you are given that you travel 80 miles in 5 minutes, you can plug  these value into the variables they are representing and solve for the constant.

Visual:

y=xk          y=miles        x=minutes         k=constant

Plug in your values and you get:

80=5k

Now, you solve for k by diving 5 on both sides, which leaves you with k=16.

Now you plug your value for k into the original equation, leaving you with y=16x

FIRST QUESTION!!!!

Option B: 1088 is the next term in the geometric sequence.

Explanation:

The sequence is 17,68,272

We need to determine the next term.

To determine the next term, let us find the common ratio between the terms.

r=\frac{68}{17} =4

r=\frac{272}{68} =4

Thus, the common ratio is r=4

And the given sequence is a geometric sequence.

To determine the next term in a geometric sequence, we always multiply the common ratio to the current term.

Hence, the current term is 272 and the common ratio is 4.

Next term = Current term × Common ratio

                =272\times4

                =1088

Thus, the next term of the geometric sequence is 1088

Therefore, Option B is the correct answer.

Kelley ate 3/5 of her brownies on Monday and 6/8 of her brownies Tuesday. If Kelley originally had 2 brownies, what fraction bro
Sergeeva-Olga [200]
<h2>Greetings!</h2>

Answer:

\frac{13}{20}

Step-by-step explanation:

First, we need to add the two fractions together. To do this we need to make the denominator a factor of both 8 and 5. Easy way to do this is to multiply each fraction by the denominator of the other fraction:

\frac{3}{5} * 8 = \frac{24}{40}

\frac{6}{8} * 5 = \frac{30}{40}

\frac{24}{40} + \frac{30}{40} = \frac{54}{40}

We can also show 2 brownies as \frac{2}{1} or \frac{80}{40}

Now we can subtract the two:

\frac{80}{40} -  \frac{54}{40} = \frac{26}{40}

Simplify the fraction down by dividing by two:

\frac{13}{20}

Which is the fraction of brownie left!
