I need help with this
1 answer:
Step-by-step explanation:
Total number of people = 60
Ratio of men to women = 1:2
Total ratio of men to women or Total parts = 1 + 2 = 3 parts
Number of men = 1/3 × 60
Number of men = 20 men
Given number of men who passed = 17 men
Therefore number of men who failed = 20 - 17
number of men who failed = 3 men
Number of women = 2/3 × 60
Number of women = 40 women
Number of people who failed = 1/5 × 60
Number of people who failed = 12 people
And number of women who failed = 12 - 3
number of women who failed = 9 women
Number of women who passed = 40 - 9
Number of women who passed = 31 women

Step-by-step explanation:
The first expression is :
Numerator = -11×2 = -22
Denominator = 3
So, answer will be :
(negative)
The second expression is:
Numerator = -11×-2 = 22
Denominator = 3
So, the answer will be :
(positive)
Hence, this is the required solution.
<h3>Conner work is correct. Jana work is wrong</h3>
<em><u>Solution:</u></em>
<em><u>Given that,</u></em>
<em><u>Conner and Jana are multiplying:</u></em>
Given Conner's work is:
We have to check if this work is correct
Yes, Conner work is correct
From given,
Use the following law of exponent
Therefore,
<em><u>Given Jana's work is:</u></em>
This is incorrect
The powers of same base has to be added. But here, powers are multiplied which is wrong
