At birthday Party girls ate 7 3/4 pizzas and the boys ate 2 1/2 pizzas. How many pizzas were eaten at my party?

10 1/4

Step-by-step explanation:

2 1/2 = 5/2

5/2 (2/2)= 10/4

7 3/4 = 31/4

10/4+31/4=41/4

41/4 = 10 1/4

huh? im pretty sure it is in 199

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
