Answer:
Number of males: 30
Number of females: 14
Step-by-step explanation:
Let x be the number of males
Males: x
Females: x - 16
x + x - 16 = 44
2x = 44 + 16
2x = 60
x = 30
Males: 30
Females 30 - 16 = 14
Let's assign a variable that is the number when multiplied by 10% it is equal to 0.1.
Well let that be x.
Now we want to convert the 10% into a decimal. To convert a percent into a decimal, simply move the % sign two places to the left and make it into a decimal point.
When we say "of" in mathematics what we really mean is to multiply.
0.10 * x = 0.1
That is the equation we need to find the value of x for.
Divide both sides by 0.10
0.10 * x = 0.1
The 0.10 on the left side cancels out.
x = 1
So, the answer to this question is if we multiply 10% by 1 we will get 0.1.
