Answer 2

Answer: 63

Step-by-step explanation:

Given

• number is 21
• and a fraction "one-thrid" or (1/3).

To Find: The number of "one-thirds" that will make 63.

Explanation:

• To solve this question, let us first try to understand what our concerned question means by "how many one thirds are there in 21? "
• For example, we all know that 4 = (1 + 1 + 1 + 1),

                                                      or, 4 = (2 + 2).

        i.e., Four 1s add upto 4, or, Two 2s add upto 4.

• We can also state the above case as (4 * 1) = 4, i.e., there are Four 1s in 4,

       or, (2 * 2) = 4, i.e., there are Two 2s in 4.

• In our concerned question, we have to similarly find out that how many One-thirds are to be added, or by what number is the fraction "one-third" needed to multiplied to obtain 21 as the result.
• We can obtain our desired answer by simply dividing 21 by (1/3), i.e.,

        $\frac{21}{\frac{1}{3} } = (21 * \frac{1}{\frac{1}{3} } )\\=(21 * 3)\\= 63.$

• Hence, 63 one-thirds are there in 21.
