1/4 = 3/5s what is the solution

Step-by-step explanation:

It may be easier for you to see what's happening here if you'd write the given 1/4 = 3/5s as:

1        3

=

 4     5s

Cross multiplying results in 5s = 12, so that s = 12/5.

If, however, you actually meant 1/4 = (3/5)s, then the solution is quite different:

1/4 = 3/5s => 1/4 = 3s/5, or

1       3s

=

 4      5

Cross multiplication results in 12s = 5, or s = 5/12.

Which did you mean, 1/4 = 3 / (5s) or 1/4 = 3s / 5?

This goes to show how important it is to use parentheses to remove any ambiguity.

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 correct answer is d
