Question

1,34,000 when rounded to the nearest 100, and 1000​

Answer 1

Step-by-step explanation:

1. (i) 3846 → 4000

We see the digit in the hundred’s place is 8, we round to the nearest multiple of thousand which is greater than the number. Hence, 3846 is nearer to 4000 than 3000.

(ii) 8039 → 8000

We see the digit in the hundred’s place is 0, we round to the nearest multiple of thousand which is smaller than the number. Hence, 8039 is nearer to 8000 than 9000.

(iii) 9985 → 10000

We see the digit in the hundred’s place is 9, we round to the nearest multiple of thousand which is greater than the number. Hence, 9985 is nearer to 10000 than 9000.

(iv) 3500 → 4000

We see the digit in the hundred’s place is 5, we round to the nearest multiple of thousand which is greater than the number. Hence, 3500 is nearer to 4000 than 3000.

(v) 16796 → 17000

We see the digit in the hundred’s place is 7, we round to the nearest multiple of thousand which is greater than the number. Hence, 16796 is nearer to 17000 than 16000.

2. Round off 47,21,54,329 to the nearest 1000.

Solution:

We choose the two multiple of 1000 just greater than and just less than 47,21,54,329 on the number line.
