There are 12000 pupils in a school. Find the ratio of the boys to the girls if the number of girl is 650

if the number of boys are x and number of girls are y ,

total number of pupils is ,

x + y = 1200

given number of girls are y = 650 ,

x + 650=1200

x = 1200-650

x = 550

Numbers boys are 550

Now the ratio of boys to girls are .

x/y = 550/650

x /y =550/ 650

x/y =11/13

The ratio of boys to the girls are = 11/13

Step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
