The percentage of births that occurred among women between the ages of 40 and 42 is 26.41%
<h3>Calculations and Parameters</h3>
First, we would add up the ages of the mothers
27 +98+239+326+389+436+468+490+460+387+286+180+102+48+19+5+1
= 3961
Thus, to find the percentage of births occurring among women between the ages of 40 and 42 was:
102+48=150
3961/150= 26.41%

We use ratios here.
For every 10 samples, the total weight is 0.01 lb.
We write
10 / 0.01.
We want to find the weight of 10,000 samples.
We write
10,000/?
These two ratios must equal each other.
(10 / 0.01) = (10,000 / ?)
If you know how to cross-multiply, then we can do that here.
0.01 * 10000 = 10 * ?
100 = 10 * ?
The unknown value is 10, which is your answer.
The first is two step
Second property
Third addition
Fourth division
Fifth variable
And the last is multiplication
Sorry I don’t know the rest
