Question

in a school the no of boys is 1800 and the no of girls is 1500 . find the ratio of (a) the no. of boys to the no. of girls (b) the no. of boys to the total no. of students in the school (c) the no. of girls to the total no. of students in the school​

Answer 1

Answer:

Step-by-step explanation:

a)the number of boys to number of girls=1800/1500=6/5=6:5

total number o students=no of boys+no of girls=1800+1500=3300

b)no of boys to total no of students = 1800:3300=18/33=6:11

c)no of girls to total no of students=1500:3300=5:11

hope this helps you friend

thanks ,pls mark as brainliest :)

Answer 2

Answer:

Ratios = a) 6 /5  , b) 6 /11 , c) 5 / 11  or  6:5 ,6:11 , 5:11

Step-by-step explanation:

According to the information provided in the question it is given as

School the no of boys = 1800

The no of girls = 1500

We need to find ratio of

(a) Number of boys to the no. of girls

(b) Number of boys to the total no. of students in the school

(c) Number of girls to the total no. of students in the school​

Total number of students = no of boys + no of girls

Substituting the values

T = 1800 + 1500

   =3300

a) Number of boys to the no. of girls

    1800 /1500

Reducing zeros to simplify the ratio

    18 / 15

Converting the lowest term we get

   6 /5  (Maximum lowest term)

   6:5

b) Number of boys to the total no. of students in the school

    1800 / 3300

Reducing zeros to simplify the ratio

   =  18 /33

   =  6 / 11            (As both are divisible by 3)

       6: 11

c) Number of girls to the total no. of students in the school​

      1500 / 3300

Reducing zeros to simplify the ratio

     =15 / 33

     = 5 / 11   ( As both are divisible by 3)

        5: 11

Hence the ratio are

a) 6 /5   =  6:5

b) 6 /11   =  6: 11

c) 5 / 11  =  5:11
