The ratio of boys to girls in a class is 2:3 There are 6 more girls than boys in the class. How many girls are in the class?

18 girls

Step-by-step explanation:

Since girls have one more unit of ratio than boys, and there are 6 more girls in class,

1 unit = 6 people

2 units = 12 people

3 units = 18 people

Therefore, plug it back in, there are 12 boys and 18 girls

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
