Test: Numbers from 21 to 99 (Part 2) - Class 1 MCQ

In descending order, the numbers are arranged from greatest to smallest. Hence, 33, 31, 29 is the correct arrangement.

In the number 58, there are 5 tens and 8 ones. The ones digit is 8, so there are 8 ones.

In the number 89, the tens digit is 8. This represents 80 in the value of the number.

The number just before 72 is 71, which is one less than 72.

In the number 99, there are 9 ones. The ones digit indicates the number of single units.

The number that comes immediately after 88 is 89. In a sequence of numbers, the next number is always one more than the current number.

The number composed of eight tens (80) and four ones (4) is 84.

In the number 76, there are 7 tens (which is 70) and 6 ones. Thus, the number of tens is 7.

The correct descending order is 21, 18, 15, 12, as it lists the numbers from the largest to the smallest.

Ascending order means arranging numbers from the smallest to the largest. Therefore, 12, 23, 45, 67 is the correct ascending order.

To compare 22 and 19, check the tens digits: 2 (in 22) is greater than 1 (in 19). Thus, 22 is greater than 19.

The number that comes immediately before 100 is 99. It is one less than 100.

To compare 23 and 30, check the tens digit. In 23, the tens digit is 2, while in 30, the tens digit is 3. Since 2 < 3, we know that 23 is less than 30.
Hence, the statement “23 is less than 30” is true.

The number that comes between 45 and 47 is 46, which is one more than 45 and one less than 47.

The number 59 is greater than 55 because in a two-digit comparison, 5 is equal in both numbers, but the ones digit of 9 is greater than 5.
