Answer 1

Given:

The number is 3091.

To find:

The number of hundreds blocks if there are no thousands block.

Solution:

The given number is 3091.

It can be written as:

$3091=3000+0+90+1$

$3091=3\times 1000+0\times 100+9\times 10+1\times 1$

$3091=3\ Thousands+0\ Hundreds+90\ Tens+1\ Ones$

There are no thousands block. So,

$3000=30\times 100$

$3000=30\ Hundreds$

Therefore, the number of hundreds blocks in 3091 is 30.
