Okay, here's an explanation of how to easily calculate 0.01% of 10 billion yen:
Steps to Understand:
-
Understand the meaning of percent (%): Percent means "out of one hundred." So, 0.01% is "0.01 out of one hundred."
-
Replace "of" with multiplication: In mathematics, "of" often indicates multiplication. Therefore, "0.01% of 10 billion yen" can be thought of as "10 billion yen × 0.01%."
-
Convert the percentage to a decimal: To make calculation easier, convert 0.01% to a decimal.
- 0.01% ÷ 100 = 0.0001
-
Perform the multiplication: Multiply 10 billion yen by the decimal form of 0.01% (which is 0.0001).
Specific Calculation:
-
Express 10 billion yen in numerals: ¥10,000,000,000
-
Express 0.01% as a decimal: 0.0001
-
Multiplication:
¥10,000,000,000 × 0.0001
To make the calculation clearer, let's think in terms of "billion" and the decimal:
- 10 billion × 0.0001
Multiplying by a decimal might be a bit confusing, so let's express 0.0001 as a fraction:
- 0.0001 = 1/10000
Therefore:
- 10 billion × (1 / 10000) = 10 billion ÷ 10000
Now it's a division problem. When you divide 10 billion by 10,000, four zeros at the end will be removed:
- ¥10,000,000,000 ÷ 10000 = ¥1,000,000
Answer:
Therefore, 0.01% of 10 billion yen is 1 million yen.
Another Easy Way to Think About It:
-
Calculate 1%: First, find 1% of 10 billion yen. 1% is one hundredth, so:
¥10,000,000,000 ÷ 100 = ¥100,000,000 (100 million yen)
-
How many times is 0.01% of 1%?: 0.01% is one hundredth (0.01 ÷ 1 = 0.01) of 1%.
-
Calculate the amount for 0.01%: Divide the amount for 1% (100 million yen) by 100:
¥100,000,000 ÷ 100 = ¥1,000,000 (1 million yen)
This method also leads to the same answer of 1 million yen.
