You put the names of all the students in your class in a paper bag. there are 14 boys and 20 girls. if you b draw a name at random, what is p(boy’s name)?

As a fraction, the answer is 7/17

In decimal form that converts to approximately 0.41176 which is 41.176%

Explanation:

We have 14 boys out of 14+20 = 34 students total

Divide the number of boys over the number of total students. Reduce the fraction as much as possible.

14/34 = (7*2)/(17*2) = 7/17

We can stop here if all your teacher wants is the fractional answer

If you want the decimal form, you would use long division or a calculator to get this approximate result

7/17 = 0.41176

moving the decimal point over 2 spots to the right converts to percent form

0.41176 ---> 41.176%

answer is : muchas/tipicas

have a nice day!

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
