Name the set(s) of numbers to which 1.18 belongs. a. rational numbers b. rational numbers, irrational numbers c. natural numbers, whole numbers, integers, rational numbers

a. rational numbers

Step-by-step explanation:

The number is between integers, so it can't be an integer or a whole number.

In general, 1.18 belongs to three sets of numbers.

Firstly, it is a rational number because it can be written in the form p/q where p and q are integers and q is not equal to zero.

1.18=

Secondly, all rational numbers are also real numbers and all real numbers are complex numbers.

But we have been given to choose from only rational numbers, irrational numbers, natural numbers or whole numbers.

So, the only answer is rational number.

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
