Explanation:
x% of y is calculated as
![(x)/( 100) * y](https://img.qammunity.org/2020/formulas/mathematics/middle-school/prf4jo69b8v3b53uneyci7rfu9r1nbylht.png)
Here calculating the given percentages:
a) 6 1/4% of $3,875
Now, 6 1/4 = 6+ 1/4 = 6.25
⇒6.25% of $3,875 =
![(6.25)/(100) * 3,875 = 242.18](https://img.qammunity.org/2020/formulas/mathematics/middle-school/h1w975jhmljb5vi616ov6xhy5bqcs7jhf9.png)
Hence, 6 1/4% of $3,875 is $242.18.
b) 16 2/3% of 96 lamps
Now, 16 2/3 = 16+ 2/3 = 16.67
⇒16.67% of 96 lamps =
![(16.67)/(100) * 96 = 16](https://img.qammunity.org/2020/formulas/mathematics/middle-school/e57zorkf99vbh8too2cba0mhueuwq13ml2.png)
Hence, 16 2/3% of 96 lamps is 16 lamps.
c) 87 1/2% of 540.72
Now, 87 1/2 = 87+ 1/2 = 87.5
⇒87.5 % of 540.72 =
![(87.5)/(100) * 540.72 = 473.11](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8t8cf5iap5k8yk43yriignsdxjmv64gp3i.png)
Hence, 87 1/2% of 540.72 is 473.11
d) 33 1/3% of 750 boys
Now, 33 1/3 = 33+ 1/3 = 33.67
⇒33.67 % of 750 boys =
![(33.67)/(100) * 750 = 252.52](https://img.qammunity.org/2020/formulas/mathematics/middle-school/r7htcdcjb11irfg0msfg0j40cskmbqap5z.png)
Hence, 33 1/3% of 750 boys is 252.52 boys
e) 66 1/2 % of 240 kg
Now, 66 1/2 = 66+ 1/2 = 66.50
⇒66 1/2 % of 240 kg =
![(66.50)/(100) * 240 kg = 159.6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g8mro5znib2f1o8us6uqolpm5axq8x64nj.png)
Hence, 66 1/2 % of 240 kg is 159.6 kg.
