Question

In which table does 39 come?

Answer 1

Hint: Basic approach for this type of problem is that we need to remember the multiplication table. Then you can easily notice that in the table of 1 comes 39 and also in the table of 3, 13 and 39 comes 39 under this table. Hence, that table of numbers is your answer.

Complete step by step solution:
Before solving this problem, first we need to understand the multiplication table and why it’s important.
A multiplication table is a mathematical table used to define a multiplication operation for an algebraic system. It is also often called the Times Table. The multiplication table is an important part of Mathematics. Learning math tables helps students in faster calculations. This is why students are told to memorize the multiplication table from a young age. Students must memorize the maths table for 1 to 20 at least.
Now, we come to the problem, that we have to find the table in such a way that 39 should comes
First, in the table of 1 we can easily say that if you multiply 1 with 39 then you will get the answer as 39. That is \[1\times 39=39\] because if any number is multiplied with 1 then you will get that number only.
Now, we come to table of 3 for that we need to write the table of 3 until we get the answer as 39
Table of 13 until it comes to 39.

\[3\]	\[\times \]	\[1\]	\[=\]	\[3\]
\[3\]	\[\times \]	\[2\]	\[=\]	\[6\]
\[3\]	\[\times \]	\[3\]	\[=\]	\[9\]
\[3\]	\[\times \]	\[4\]	\[=\]	\[12\]
\[3\]	\[\times \]	\[5\]	\[=\]	\[15\]
\[3\]	\[\times \]	\[6\]	\[=\]	\[18\]
\[3\]	\[\times \]	\[7\]	\[=\]	\[21\]
\[3\]	\[\times \]	\[8\]	\[=\]	\[24\]
\[3\]	\[\times \]	\[9\]	\[=\]	\[27\]
\[3\]	\[\times \]	\[10\]	\[=\]	\[30\]
\[3\]	\[\times \]	\[11\]	\[=\]	\[33\]
\[3\]	\[\times \]	\[12\]	\[=\]	\[36\]
\[3\]	\[\times \]	\[13\]	\[=\]	\[39\]

From the above table of 3 we can say that 39 comes in the 13th row of table 3.
Similarly, we can also find the table of 13 as well as 39
Table of 13 is given below until it reaches the answer as 39.

\[13\]	\[\times \]	\[1\]	\[=\]	\[13\]
\[13\]	\[\times \]	\[2\]	\[=\]	\[26\]
\[13\]	\[\times \]	\[3\]	\[=\]	\[39\]

From this table of 13 we can see that 39 comes in the third row of table 13.
Now, Table of 39 is given below until it reaches the answer as 39.

\[39\]

\[\times \]

\[1\]

\[=\]

\[39\]

Here, in the first row, we can see that 39 comes in the table of 39 as well.
Therefore, 39 comes in the table of 1, 3, 13 and 39.

Note: While solving this type of problem, it is always advisable that we need to write the multiplication table to solve this problem. Some students find it very difficult to remember the tables. Especially, when it comes to learning the multiplication table for bigger numbers, it gets more difficult. For that to write the multiplication table there has to be some trick to remember the multiplication table. Trick is given as: Add the number to itself (in other words, double it) For Example: \[2\times 9=9+9=18\]. Every multiplication has a twin, which may be easier to remember. That means if you forgot \[8\times 2\]then you might remember \[2\times 8=16\]. This way, you only have to remember half the table. These are some basic tricks to write the multiplication table.
