To write 1.86 as a fraction, follow these steps:
-
Separate the whole number from the decimal. The whole number is 1, and the decimal part is 0.86.
-
Convert the decimal part (0.86) into a fraction. Since 0.86 has two decimal places, you can express it as: \[ 0.86 = \frac{86}{100} \]
-
Simplify the fraction \(\frac{86}{100}\). Both 86 and 100 can be divided by 2: \[ \frac{86 \div 2}{100 \div 2} = \frac{43}{50} \]
-
Now, combine the whole number with the fractional part: \[ 1.86 = 1 + 0.86 = 1 + \frac{43}{50} \]
-
Convert the whole number into a fraction with the same denominator: \[ 1 = \frac{50}{50} \]
-
Add the two fractions: \[ 1.86 = \frac{50}{50} + \frac{43}{50} = \frac{50 + 43}{50} = \frac{93}{50} \]
Therefore, \(1.86\) as a fraction is \(\frac{93}{50}\).
