Caroline, Colin & Sarah share some money. Caroline gets 1 /9 of the money. Colin and Sarah share the rest in the ratio 1:3.

What proportion does Colin get?

Answer:

Colin gets  \frac{2}{9} of the total money

Step-by-step explanation:

If we let the total amount be "90" (or any multiple of 9), then the solution gets much easy.

Let total money be 90.

Caroline gets 1/9, so that is:

1/9 * 90 = 10

Remaining is 90 - 10 = 80

This 80 is divided in the ratio 1:3, that means Colin gets 1 part and Sarah gets 3 part. That is 1 + 3 = 4 parts altogether.

80 divided in 4 parts is 80/4 = 20 each part.

Colin gets 1 part, that is 1 * 20 = 20

Colin gets 20 OUT OF 90 (total initial).

<em>What proportion is that? We simply divide and reduce!!</em>

<em />

20/90 = 2/9

Colin gets  \frac{2}{9} of the total money

A baseball team wants a pitcher no more 150 innings during a season. So far, the pitcher has pitched <img src="https://tex.z-dn.
butalik [34]

Answer:

C. 6 because any answer besides that is too low or too high.

Step-by-step explanation:

110.25 pitches so far- 150 at max. 5.75 pitches per game.

4: 4x5.75 = 23

110.25 + 23 = 133.25

5. 5x5.75 = 28.75

110.25 + 28.75 = 139

6: 6x5.75 = 34.5

110.25 + 34.5 = 144.75

7: 7x5.75 = 40.25

110.25 + 40.25 = 150.50 > which rounds up to 151

How do you convert a whole number to a fraction?
Maslowich

Answer:

Step-by-step explanation:

Example 1: Changing the whole number 5 into a fraction.

Take the whole number (5), add a line below it (/), then add a 1 to the denominator.

5 = 5/1

Example 2: Changing the whole number 5 into a fraction.

Take the whole number (5), multiply it by 2 add a line below it (/), then add a 2 to the denominator.

5 = (5*2)/2 = 10/2

***This can be reduced to 5/1***

Example 3: Changing the whole number 5 into a fraction.

Take the whole number (5), multiply it by 3 add a line below it (/), then add a 3 to the denominator.

5 = (5*3)/3 = 15/3

***This can also be reduced to 5/1***

If you follow the pattern, you will realize all whole numbers are fractions already.

They are fractions with a denominator of 1. This fraction can be manipulated with all of the same standard rules you would traditionally use with fractions, even when the denominator isn’t shown.

A fraction is simply a way to describe portions of a whole. The denominator simply tells you how many pieces to break the whole into. When the denominator is 1, you are breaking the whole into one piece (or not breaking it apart at all.

I hope this helps.

Which expression is irrational?
Mrrafil [7]

Answer:

\sqrt{50}

Step-by-step explanation:

An irrational number is a number that isn't a whole number (integer).

\sqrt{50} = 7.07

\sqrt{1} = 1

\sqrt{25 = 5

\sqrt{9} = 3

The first one is the only one that isn't an integer. So it is the answer.
