The ratio
b : g = 5 : 4
the sum of the ratio = 5 + 4 = 9

Find the number of girls
girls = the ratio of girls/the sum of the ratio × the sum of students
girls = 4/9 × 180
girls = (4 × 180)/9
girls = 720/9
girls = 80

There are 80 girls

Boys to girls ratio - 5 to 4.
5 + 4 = 9.
180 divided by 9 equals 20.
20 times 4 equals 80.

Crank
A) ( 25 / 100 ) * 100 = 25 m ;
b) ( 30 / 100 ) * ( 1205 / 100 ) = 36150 / 10000 = 3615 / 1000 = 3,615 km ≈ 3,62 km ;
c) ( 40 / 100 ) * 60 = ( 4 / 10 ) * 60 = 4 * 6 = 24 m^2 ;
d) 3 1 /3 = 10 / 3 ;
( 32 / 100 ) * ( 10 / 3 ) = 320 / 3 = 106,66 kg;
e) ( 1 / 10 ) ÷ 100 * 10 = ( 1 / 10 ) * ( 1 / 100 ) * 10 = 1 / 100 = 0,01 l ;

Good luck !

Step-by-step explanation: firtst u need to find the dot product of both a and  b (a.b).

then the magnitude of both (√a ,√b)

then u substitute them into the equation

∅=cos-1(a.b/√a x √b)

u will find it to be error bcoz  it will be (0/√3 x 0)
