The number of clocks that are not defective is an illustration of proportions
Of the 10000 clocks, 9250 are probably not defective
<h3>How to determine the number of clocks that are not defective?</h3>
From the complete question, we have the following parameter:
15 out of 200 clocks are defective
The above means that the number of clocks that are not defective is:
Not defective = 200 - 15
Not defective = 185
Express as percentage
Not defective = 185/200
Not defective = 92.5%
In 10,000 the number of clocks that are not defective would be:
Not defective = 92.5% * 10000
Not defective = 9250
Hence, 9250 of the 10000 clocks are probably not defective

Answer:
a/b= 2/15
Explanation:
3a +b
----------- = 7/5
b
<h2>now cross multiple both side</h2>
5(3a+b)=7 x b
15a +5b = 7b
15a = 7b-5b
15a = 2b
15a/2b = 1
a/b x 15/2 =1
<h3>multiple both side
by 2/15</h3>
we get,
a/b = 2/15
hope you have no doubt now !
<h2>we get ,</h2>
