12 because if u multiply 3*4 it is 12 and 4*3 is 12 so they both have 12 in common.

To find common denominators
you may take each denominator and provide the acceptable factors.

factors of 3: 1 , 3 , 6 , 9 , 12....ETC
factors of 4: 1 , 2 , 4 , 8 , 12...ETC

Note that they both have a common number of 12

So you will multiply the 1st fraction by 4 and the 2nd by 3

4(1/3) = 4/12
3(1/4) = 3/12

no need for the last part unless if you are proceeding with different properties.

Julia bought stock at $281/8 per share. The value of each share increased by $65/8. How much is each share of stock now worth?

const2013 [10]

The worth of the share of stock is $ $34\frac{3}{4}$ .

<h3>What is the worth of the stock now?</h3>

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A mixed fraction is a fraction that is made up of a whole number and a proper fraction. A proper fraction is a number where the numerator is less than the denominator.

The worth of the stock now = purchase price + increase in the share price

28 1/8 + 6 5/8

$34 \frac{1 + 5}{8}$

$34\frac{6}{8}$ = $34\frac{3}{4}$

There are 34 Pre-K children and 29 kinder garden children on the playground, some boys and some girls. The ratio of boys to girl

Natali [406]

There are 27 boys on the playground.

Step-by-step explanation:

No. of Pre-K children = 34

No. of kindergarten children = 29

Total no of children = 29+34 = 63

Ratio of boys to girls = 3:4

Total ratio = 3+4 = 7

Therefore,

boys proportion = $\frac{3}{7}$

Total number of boys = $\frac{3}{7}\ of\ total\ number\ of\ children$

$Total\ number\ of\ boys = \frac{3}{7} *63\\Total\ number\ of\ boys = \frac{189}{7} \\Total\ number\ of\ boys = 27$

There are 27 boys on the playground.

You have also set up a card game in which a player picks a card from a standard deck of 52 cards. The player wins if these two e

Alenkinab [10]

First, let's count:

there are 26 possible outcomes for E1 (black card)

there are 4x9 = 36 possible outcomes for E2, to pick a numbered card (any color)

there are 2x9 =18 possible outcomes for E1 (black) AND E2 (numbered, spade + clower)

the probability of E1 AND E2 is the ratio of the count of possible outcomes for E1 + E2 and the count of all possible outcomes (52 choices to pick a card from the deck):

P(E1 and E2) = 18/52 (34.6%)

And as asked:

P(E1) = 26/52 = 1/2 (50%)

P(E2) = 36/52 = 9/13 (69.2%)
