What is 19% of 2,300?
Correct. [[snippet]] You can think of $$19\%$$ as $$20\% - 1\%$$: > $$19\% \times 2{,}300 = 20\% \times 2{,}300 - 1\% \times 2{,}300$$ Use the 10% block: >10% of 2,300 is 230, so 20% of 2,300 is 460. Now use the 1% block: >1% of 2,300 is 23. Finally, subtract these values: > $$20\% \times 2{,}300 - 1\% \times 2{,}300 = 460-23 = 437$$
