Choose the best compatible numbers to find an estimated product or quotient.
2,127 ÷ 405
a) explain why you choose your compatible numbers.
b) what place value did you round to for each of your compatible numbers?
c) perform the division using your compatible numbers.

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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
