Jacinta is working on a puzzle that has 403
pieces she has completed 1/4 of the puzzle. how many pieces does she have left to place in the puzzle?

About 302 pieces to go!

Step-by-step explanation:

Divide 403 by 4 to get 1/4 of the amount done, or 100.75. Multiply 100.75 by 3 to get 3/4 (the remainder) of the puzzle, which is 302.25. Round this down to 302 pieces.

Hope this helps! :)

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

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
