Answer 2

Given number: 975.

To find: the maximum group of 10s can you subtract from 975 without actual division.

​Solution:

Write the given number in expanded form.

$\[\begin{array}{l}975 = \left( {9 \times 100} \right) + \left( {7 \times 10} \right) + 5 \times 1\\ \Rightarrow 975 = \left( {9 \times 10 \times 10} \right) + \left( {7 \times 10} \right) + 5 \times 1\\ \Rightarrow 975 = \left( {90 \times 10} \right) + \left( {7 \times 10} \right) + 5 \times 1\end{array}\]$

Observe that, there are 90 tens and 7 tens.

$\[\begin{array}{l} \Rightarrow 975 = 90\,tens\, + \,7\,tens\\ \Rightarrow 975 = 97\,tens\end{array}\]$

Hence, 97 tens could be subtracted from 975 without actual division.
