A student was asked to add the fractions below. 33 + 1 For their first step the student wrote the problem as 9/24 + 10/24 respond to all the following
Why they chose 24 as the denominator
How they were able to rewrite each fraction
complete addition problem

see below

Step-by-step explanation:

a)The least common multiple of 8 and 12 is 24

3*8 =24

2*12 = 24

b)

3/8 * 3/3 =9/24

5/12 * 2/2 = 10/24

c)

9/24 + 10/24 =19/24

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
