It was cloudy 12 out of 30 days in April. Which value is equivalent to the fraction of days it was cloudy in April? (Not college its middle school btw)

You included no options so I will list some of the various fractions and decimal that are equivalent to the fraction of days it was cloudy in April.

In fraction form, the value can be simplified to;

In decimal form, the value would be;

= 12 ÷ 30

= 0.4

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
