Answer:

8 hours

Step-by-step explanation:

We can use a ratio to solve

12 hours    x hours

----------   = ------------

93 dollars    62 dollars

Using cross products

12 * 62 = 93x

Divide each side by 93

12*62/93 = 93x/93

8 = x

8 hours

Caroline, Colin & Sarah share some money.
Alex787 [66]

Caroline, Colin & Sarah share some money.Caroline will get \dfrac{2}{3}  when Caroline, Colin & Sarah share some money.

<h3>What is the ratio?</h3>

The ratio defined as the sharing of the two or three things or it represent that one thing or number is how many times to the other.

One part is excluded in the problem. That part is:

"Caroline gets \dfrac{1}{9} of the money."

If Caroline gets 1/9th, then remaining is:

1-\dfrac{1}{9}=\dfrac{8}{9}

Colin and Sarah share in ratio 3 is to 1, that means 3 + 1 = 4 parts...

8/9th in 4 parts means, each part is:

\dfrac{\dfrac{8}{9}}{4}=\dfrac{2}{9}

We know Colin gets "3" parts of the total, each part is (2/9)th, so 3 parts would be:

3\times \dfrac{2}{9}=\dfrac{6}{9}=\dfrac{2}{3}

Colin gets  \dfrac{2}{3} money when three of them share money.

Solve for x. −18 = −2/3 x
vredina [299]

Answer:

x = 27

Step-by-step explanation:

To isolate x, we can multiply it by the reciprocal of the fraction (-3/2). We do the same to the -18.

Through cross-multiplication, -18/1 x -3/2 simplifies into -9/1 x -3/1 (because 2 goes into 2 once and 2 goes into -18 -9 times).

-9 x -3 = 27; therefore, x = 27
