Which statement is true?
defon

Answer:

b. Multiplying decimals less than one is finding a part of a part.

Step-by-step explanation:

A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is \frac{1}{2}.

The product of a part and another part can be expressed as;

\frac{1}{3} x \frac{2}{3} = \frac{2}{9}

or,

\frac{1}{2} x \frac{1}{2} = \frac{1}{4}

or,

\frac{1}{2} x \frac{2}{3} = \frac{2}{6} = \frac{1}{3}

The three examples shows: a part x a part.

Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.
