Answer: 0.05
Step-by-step explanation: To write 2/40 as a decimal, we first write the fraction in lowest terms by dividing both the numerator and the denominator by the greatest common factor of 2 and 40 which is 2 and we get 1/20.
In order to write 1/20 as a decimal, we need to find a fraction equivalent to 1/20 with a 100 in the denominator. Notice that if we multiply both the numerator and the denominator of 1/20 by 5, we get the equivalent fraction 5/100 which we can now write as a decimal.
The hundredths place is two places to the right of the decimal point so we can write 5/100 as 0.05.
Therefore, 2/40 is equivalent to 0.05.
