1/4 of the total girls = 16
1/4x = 16
x = 16 * 4
x = 64 girls
1/8 of the total boys = 7
1/8x = 7
x = 7 * 8
x = 56 boys
for a total of (64 + 56) = 120 students <===
First we convert the m to km by dividing the number by 1000. 1000m = 1 km.
150,000,000,000 / 1000 = 150,000,000 km
Now we divide 150,000,000/11,000,000 = 13.6363636364 au.
