Erica can run \dfrac{1}{6} 6
1
​
start fraction, 1, divided by, 6, end fraction of a kilometer in a minute. Her school is \dfrac34
4
3
​
start fraction, 3, divided by, 4, end fraction of a kilometer away from her home.
At this speed, how long would it take Erica to run home from school

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

55% are girls and 45% are boys : ) hope this
