Place Value | MCQs

Explanation

A seven-digit number starts from 1,000,000 and goes up to 9,999,999.

1000000 is the smallest possible number with exactly seven digits.

Explanation

The greatest six-digit number is 999999 (all digits are 9).

Any higher number becomes a seven-digit number (starts from 1000000).

Explanation

Converting all to decimals:

7:9 = 0.777

2:3 = 0.666

5:6 = 0.833

3:4 = 0.75

Correction: Correct answer: 5:6

Explanation

Smallest 3-digit number is 100; smallest 2-digit number is 10.

Their product is 100 × 10 = 1000.

Explanation

In the number 3794, the digit 9 is in the hundreds place.

To understand place value, each digit in a number occupies a specific position that represents its value relative to the place it occupies. In the number 3794, the digit 9 is in the hundreds place, which means it represents 9 hundreds or 900.

So, the place value of 9 in the number 3794 is indeed hundreds.

Explanation

In the number 6,985,621, the digit 2 is in the tens place.

Therefore, its place value is 2 × 10 = 20.

Explanation

In large numbers, commas are placed after every three digits starting from the right.

For example, 1,000 and 10,000,000 have commas after every three digits.

Explanation

Adding 0 to the right of a decimal (after the last digit) does not change its value.

For example, 3.5 = 3.50 = 3.500 — all represent the same number.

Explanation

Expanded form is writing a number as the sum of the place values of its digits.

For example, 345 would be written as 300 + 40 + 5 in expanded form.

Explanation

The place value of 9 in 0.06945 is 9/10000, since the 9 is in the ten-thousandths place.

Here's how the place values work in this number:

•  0 is in the ones place
•  0 is in the tenths place
•  6 is in the hundredths place
•  9 is in the thousandths place
•  4 is in the ten-thousandths place
•  5 is in the hundred-thousandths place

So, the 9 is in the thousandths place, making its place value 9/10000.
