We were given:
[tex]70\times300[/tex]We will proceed to solve this as shown below:
[tex]\begin{gathered} 70\times300 \\ We\text{ will reduce this pro}duct\text{ into easily multipliable units, we have:} \\ =70(100+100+100) \\ =7,000+7,000+7,000 \\ =21,000 \\ \\ \therefore70\times300=21,000 \end{gathered}[/tex]
