Whoa !
Before we talk about 'how', we need to agree on 'what'.
Are you saying that you have the problem ' 6 x 3/2 ',
and you know that the answer is ' 21 ' and you want to know
how the answer was worked out ?
You can stop right there.
To multiply a fraction by a whole number, just multiply the
numerator of the fraction by the whole number. Then
simplify the fraction if it needs simplifying.
6 x 3/2 = (6 x 3) / 2 = 18/2 .
To simplify 18/2 , divide top and bottom by 2.
Then you have ' 9 ' , and that's the answer.
' 6 x 3/2 ' is equal to 9 , not 21 .
