Place in order from the fastest to the slowest

A. 12.5, 12 1/4, 12.2

Step-by-step explanation:

I'm not sure if this is correct but I got this but turning all of these into decimal form and writing them fuller which gave me 12.50, 12.25, and 12.20. I turned 1/4 into .25 because .25 is 1/4 of 100. I was taught that there is always a 0 after numbers so .5 is actually .50 and .2 is .20 which lead me to putting them in order.

So in conclusion, after putting them in decimal form, i just listed them according to fastest to slowest or greatest to least.

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

yes
