What would this question look like after we change the mixed number to improper & use KCF to rewrite the question?

iris [78.8K]

Answer:

The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.

Step-by-step explanation:

We need to change the mixed number to improper & use KCF to rewrite the question.

The expression is: $3\frac{1}{2}\div\frac{1}{3}$

First converting mixed fraction into improper fraction

Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2

Solving:

$3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}$

Using KCF

KCF stands fro Keep it, Change it, Flip it.

It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)

So, our expression will be

$=\frac{7}{2}\times \frac{3}{1}$

So, The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.
