Method 1: The Decimal Method (Fastest for Calculators)<\/h2>\r\n\r\n

Step 1:<\/strong> Convert the percentage to a decimal by dividing by 100:<\/p>\r\n\r\n

\r\n 80 \u00f7 100 = 0.80<\/strong>\r\n <\/div>\r\n\r\n

Step 2:<\/strong> Multiply the decimal by the target number:<\/p>\r\n\r\n

\r\n 0.80 \u00d7 50 = 40<\/strong>\r\n <\/div>\r\n\r\n
\r\n\r\n

Method 2: The Fraction Method<\/h2>\r\n\r\n

Step 1:<\/strong> Write 80% as a fraction over 100:<\/p>\r\n\r\n

\r\n 80\/100 = 4\/5<\/strong>\r\n <\/div>\r\n\r\n

Step 2:<\/strong> Multiply the fraction by 50:<\/p>\r\n\r\n

\r\n (4\/5) \u00d7 50 = 200\/5 = 40<\/strong>\r\n <\/div>\r\n\r\n
\r\n\r\n

Method 3: The Mental Math \"10% Rule\" (No Pen Needed)<\/h2>\r\n\r\n

Step 1:<\/strong> Find 10% of 50 by moving the decimal one place to the left:<\/p>\r\n\r\n

\r\n 10% of 50 = 5<\/strong>\r\n <\/div>\r\n\r\n

Step 2:<\/strong> Multiply by 8 to get 80%:<\/p>\r\n\r\n

\r\n 5 \u00d7 8 = 40<\/strong>\r\n <\/div>\r\n\r\n

Bonus: The Symmetry Trick<\/h3>\r\n\r\n

You can also use the Symmetry Trick<\/strong> to calculate percentages more quickly:<\/p>\r\n\r\n

\r\n x% of y = y% of x<\/strong>\r\n <\/div>\r\n\r\n

Finding 80% of 50<\/strong> is identical to finding 50% of 80<\/strong>.<\/p>\r\n\r\n

Since 50% simply means half, half of 80 is:<\/p>\r\n\r\n

\r\n 80 \u00f7 2 = 40<\/span>\r\n

Final Answer: 40<\/strong><\/p>\r\n <\/div>\r\n\r\n<\/div>\r\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
