How to multiply a whole number by a fraction like 4/6 x 4 etc .

jeka57 [31]

Answer:

See below, please!

Step-by-step explanation:

To multiply a whole number by a fraction, set up both numbers so that they have a numerator and denominator, multiply the corresponding parts, and simplify.

Ex: $\frac{4}{6}*\frac{4}{1}$ . Both of them are in fraction form, right? Now multiply the numerator and denominator together. Doing this, you get 16/6. Now simplify. Look for a common factor between both the numerator and denominator. We can see that one common factor is 2. So, our simplified fraction is 8/3.
