A jar contains 900 beans. Of all the beans, 7/10 are white beans and the rest are azuki beans. What is the ratio of white beans to azuki beans?

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

i think the answer is b

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

did u ever get the answers? i need
