57.72 ÷ 0.74 with the equation.

x=77.39

Step-by-step explanation:

57.72/.74

is 77.39189 but round it to 77.39

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
