Answer: 7.75
Step-by-step explanation: In order to write 31/4 as a decimal, we need to find a fraction equivalent to 31/4 with a 100 in the denominator. Notice that if we multiply both the numerator and denominator of 31/4 by 4, we get the equivalent fraction 775/100 which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point so we can write 775/100 as 7.75.
Therefore, 775/100 is equivalent to 7.75.
