Answer:

2/6 is read as "2 out of 6" or "2 in 6"

Step-by-step explanation:

Since there are 6 sides on a dice you have a 2 in 6 chance of rolling either a 4 or a 6. The probability of rolling one over the other would be 1/6

Hope this helps!

3/4 of a number is 27. What’s the number?

Artyom0805 [142]

Hello from MrBillDoesMath!

Answer:

Discussion:

From the problem statement

(3/4) x = 27

where "x" is the number to be found.

Multiply both side of the above equation by (4/3):

(4/3)(3/4)x = 27 (4/3) => as (4/3)(3/4) = 1

1x = 27 * 4/3 = 108/3 = 36

Thank you,

The ratio of petunias to geraniums in the greenhouse was 15 to 2. Combined there was 1020. How many geraniums were in the greenh

Mrac [35]

in short, we simply split the total amount by the given ratio, so we'll split or divide 1020 by (15 + 2) and then distribute accordingly.

$\bf \cfrac{petunias}{geraniums}\qquad 15:2\qquad \cfrac{15}{2}~\hspace{7em}\cfrac{15\cdot \frac{1020}{15+2}}{2\cdot \frac{1020}{15+2}}\implies \cfrac{15\cdot \frac{1020}{17}}{2\cdot \frac{1020}{17}} \\\\\\ \cfrac{15\cdot 60}{2\cdot 60}\implies \cfrac{900}{120}\implies \stackrel{petunias}{900}~~:~~\stackrel{geraniums}{120}$
