When multiplying and/or dividing fractions, answer if each of the statements below are TRUE or FALSE. 1: The denominators MUST be the same.

2: You must convert mixed numbers into improper fractions before multiplying or dividing.

3: You can keep mixed numbers when performing multiplication or division.

4: Numerators must be multiplied by numerators and denominators must be multiplied by denominators.

1. Only true to division. Most likely though when multiplying it's more helpful to have the denominators the same.

2. True

3. False

4. True

answer: i'm not sure

step-by-step explanation:

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
