There are eight boxes. Each box holds one sweater. There are 3 blue, 2 brown, 1 green, and 2 red sweaters. What is the probabili
Reil [10]

3 + 2 + 1 + 2 = 8, which is the amount of sweaters.
The probability of a brown sweater is 2 / 8 = 0.25
And the probability of a green sweater is 1 / 8 = 0.125.

Multiply the two probabilities together to get the probability of choosing brown then green:
0.25 * 0.125 = 0.03125.

To convert a decimal to fraction, you multiply the numerator and denominator, or in this case \frac{0.03125}{1} by 1000 which gets \frac{31.25}{1000}

Which can be simplified to:
\frac{1}{32}.

Hope this helps.

Find the difference of 3/4 and 1/28.
adell [148]

3/4 = 21/28 after multiplying top and bottom of 3/4 by the value 7

3*7 = 21 and 4*7 = 28

The goal is to get 3/4 into an equivalent fraction that has 28 as the denominator.

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

So 3/4 - 1/28 is the same as 21/28 - 1/28

The denominators are the same. We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28

We have

21/28 - 1/28 = (21-1)/28 = 20/28

Now reduce 20/28 as much as possible. Divide both parts by the GCF 4

20/4 = 5

28/4 = 7

The final answer is 5/7
