Sarah has saved 242 pound coins. She puts the pound coins into bags.
There are 20 pound coins in each full bag of coins.

Sarah is going to take all her full bags of coins to the bank.
She can only take up to 5 full bags of coins to the bank each day.

Sarah wants to go to the bank on as few days as possible.

On how many days will Sarah need to go to the bank?

i can you answer this question sweetie!

step-by-step explanation:

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
