Final answer:
To express 7 whole number 1/4 years to months, we multiply 7 by 12 to get the number of months in the whole years and multiply 1/4 by 12 to get the number of months in the fractional year. Then, we add the two results together.
Step-by-step explanation:
To express 7 whole number 1/4 years in months, we need to consider that there are 12 months in a year. First, we convert the whole number 7 to months by multiplying it by 12, which gives us 84 months. Then, we convert 1/4 year to months by multiplying it by 12/1, which gives us 3 months. Finally, we add the two results together to get the total number of months: 84 + 3 = 87 months.
