If 12 men are needed to run 4 machines. How many men are needed to run 20

Harrizon [31]

Answer:

Step-by-step explanation:

If 12 men are needed to run 4 machines. How many men are needed to run 20

we can solve with an equation

12 : 4 = x : 20

x = 12 * 20 : 4

x = 240 : 4

x = 60

----------------------------

check

12 : 4 = 60 : 20

3 = 3

the answer is good

In the voting for City Council Precinct 5, only 1/2 of all eligible voters cast votes. Shelley received 3/10 of the votes and Mo

Ronch [10]

Answer: Fraction of all eligible voters voted for Shelly is $\dfrac{3}{20}$ .

Morgan received the most votes .

Step-by-step explanation:

Given : The fraction of all eligible voters cast votes = $\dfrac{1}{2}$

The fraction of votes received by Shelly = $\dfrac{3}{10}$ (1)

Now, the fraction of all eligible voters voted for Shelly is given by :_

$\dfrac{3}{10}\times\dfrac{1}{2}=\dfrac{3}{20}$

Thus, the fraction of all eligible voters voted for Shelly is $\dfrac{3}{20}$ .

The fraction of vote received by Morgan= $\dfrac{5}{8}$ (2)

To compare the fractions given in (1) and (2), we need to find least common multiple of 10 and 8 .

LCM (10, 8)=40

Now, make denominator 40 (to make equivalent fraction) in (1), (2) we get

Fraction of all eligible voters voted for Shelly = $\dfrac{3\times4}{10\times4}=\dfrac{12}{40}$

Fraction of all eligible voters voted for Morgan = $\dfrac{5\times5}{8\times5}=\dfrac{25}{40}$

Since, $\dfrac{25}{40}>\dfrac{12}{40}$ [By comparing numerators]

Therefore, Morgan received the most votes .
