It took reza 2 hours to edit 6 math
problems. at that rate, how many math
problems could reza edit in 45 hours?

135

Step-by-step explanation:

My method 45 hours - 1  so i could divide by 2 because its 2 hours every 6 problems and 1 hour would be 3 math problems we can add that to the total

44 / 2 = 22, 22 * 6 = 132, 132 + 3 = 135

Alternate method

45 * 3 = 135

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
