1. 1.5 and 3.5
2. both equations because they share these particular points
If you choose one person from the group, you have a 12/20 chance of them being a girl. Now, if the first person is a girl, we have one less girl and one less person to choose from. So, the new probability for the second person is 11/19.
Then, we multiply the chances
12/20 * 11/19
3/5 * 11/19
33/95
Answer:
in this problem we do a comparison case t i.e if 1/12 he writes 1/6 of page what about 1 page
1/12minute = 1/6
? × 1 then we cross multiply
(1*1/12) ÷ 1/6 =1/12*6 = 1/2 minute
The value of g from the given proportion is 227.2
<h3>Ratio and proportions</h3>
Fractions are written as a ratio of two integers. For instance a/b is a fraction where a and b are integers.
Given the following proportion shown below;
143/g = 540/858
In order to determine the value of g, we will cross multiply to have:
540g = 143 * 858
Simplify
540g = 122694
Divide both sides by 540
540g/540 = 122694/540
g = 122694/540
g = 227.2
Hence the value of g from the given proportion is 227.2
