Forming 2-Digit Numbers | Forming Best and Smallest 2-Digit Quantity

We’ll study forming 2-digit numbers.

What number of 2-digit numbers might be fashioned utilizing the digits 2
and seven?

There are two methods to make 2-digit numbers utilizing the given
digits.

I. By repeating the digits – 22 and 77

II. With out repeating the digits – 27 and 72

Thus, there are
4 2-digit numbers that may be made utilizing the digits 2 and seven.

Forming Best 2-Digit
Quantity:

For Instance:

1. Construct the best 2-digit quantity attainable utilizing the
digits 5 and 1.

Step 1: Begin with the best digit within the biggest place.
Since, 5 > 1, put 5 within the tens place.

Step 2: Now put the following biggest digit within the ones place.

If repetition is allowed, the best 2-digit quantity is 55.

If repetition shouldn’t be allowed, the best 2-digit quantity is
51.

Since 55 > 51, the best 2-digit quantity attainable utilizing
the given digits is 55.

 

2. Construct the best 2-digit quantity attainable utilizing the
digits 8 and 4.

Step 1: Begin with the best digit within the biggest place.
Since, 8 > 4, put 8 within the tens place.

Step 2: Now put the following biggest digit within the ones place.

If repetition is allowed, the best 2-digit quantity is 88.

If repetition shouldn’t be allowed, the best 2-digit quantity is
84.

Since 88 > 84, the best 2-digit quantity attainable utilizing
the given digits is 88.

Forming smallest 2-digit
quantity

For Instance:

1. Construct the smallest 2-digit quantity attainable utilizing the
digits 2 and 1.

Step 1: Begin with the smallest digit within the biggest place.
Since, 1 < 2, put 1 within the tens place.

Step 2: If repetition is allowed, the smallest 2-digit
quantity is 11.

If repetition shouldn’t be allowed, the smallest 2-digit quantity is
12.

Since 11 < 12, the smallest 2-digit quantity attainable utilizing
the given digits is 11.

 

2. Construct the smallest 2-digit quantity attainable utilizing the
digits 7 and three.

Step 1: Begin with the smallest digit within the biggest place.
Since, 3 < 7, put 3 within the tens place.

Step 2: If repetition is allowed, the smallest 2-digit
quantity is 33.

If repetition shouldn’t be allowed, the smallest 2-digit quantity is
37.

Since 33 < 37, the smallest 2-digit quantity attainable utilizing
the given digits is 33.

3. Construct the smallest 2-digit quantity attainable utilizing the
digits 6 and 0, with out repeating any of the digits.

0 < 6, however beginning with zero makes 06, which isn’t a
2-digit quantity.

Therefore, we start with the following smallest digit which is 6.

Now put the following smallest digit which is 0 within the ones
place. Thus, 60 is the smallest 2-digit quantity fashioned utilizing the given digits.
