Total: $445,045+1,082,837+1,208,405+962,179+499,916+105,071+7,349=4,310,802$
The relative frequency for "15–19" is $\frac{445,045}{4,310,802}\approx0.1032$
The relative frequency for "20–24" is $\frac{1,082,837}{4,310,802}\approx0.2512$
The relative frequency for "25–29" is $\frac{1,208,405}{4,310,802}\approx0.2803$
The relative frequency for "30-34" is $\frac{962,179}{4,310,802}\approx0.2232$
The relative frequency for "35–39" is $\frac{499,916}{4,310,802}\approx0.1160$
The relative frequency for "40–44" is $\frac{105,071}{4,310,802}\approx0.0244$
The relative frequency for "45–49" is $\frac{7,349}{4,310,802}\approx0.0017$
The percentage of live births to women 40 to 44 years old is the relative frequency of the 6th class : $0.0244=2.44$%
The percentage of live births to women 24 years or younger is the summation of the relative frequencies of the 1st and 2nd classes: $0.1032+0.2512=0.3544=35.44$%
