Carlos bought 515 Euros for his holiday to Germany. He spent £412 to obtain these Euros. Write the ratio of pounds to Euros in the form 1: n.

412:515

Step-by-step explanation:

Given data

Carlos bought 515 Euros

He spent £412

We want to find the ratio of the purchase to the amount spent

In the form 1:n

We have our ratio of pound to euros has

412:515

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
