Test: 3-Digit Numbers- 1

89 comes before 156.
Hence, 89 is less than 156.

134 < 156 <176 <192. The abacuses show number 134, 156, 176 and 192 in ascending order.
As they are placed from smallest to greatest.

173 > 172 > 162 > 126
As the numbers are arranged from greatest to smallest.
The abacuses show the numbers 173, 172, 162 and 126 in descending order.

198 comes after 189.
Hence, 198 is greater than 189.

145 is equal to 145.

198 comes just after 197.
Hence, 198 is greater than 197.

156 comes before 165.
Hence, 156 is smaller than 165.

The number shown on the abacus is 143. 154 comes after 143.
Hence, 154 is greater than 143.

The first two digits of the three-digit number that Riya wrote is 1 and 7.
The number written by Riya is greater than 176.
When we write 8 as the last digit after 17, we get 178.
178 is greater than 176.
So, the digit at the ones place of the number was 8.
Hence, Riya erased 8 by mistake.

In ascending order the numbers are arranged from smallest to greatest.
Hence, 113 < 124 < 128 < 129 are arranged in ascending order.
