Answer:
1092/365 or ≈3
Step-by-step explanation:
In one year, there are 365 days, so there are 365/7 weeks in a year. In order to find how many years 156 weeks is, you need to see how many times 365/7 fits into 156, or what 156 ÷ 365/7 is:
156/1 ÷ 365/7 = 156/1 × 7/365 (because a ÷ b/c = a × c/b)
= 1092/365
1092/365 is the most simplified answer because 1092 and 365 don't share factors, but if you convert this fraction to decimal, you get ≈2.99 (rounding to hundredths), so it can be 2.99 or 3 depending on whether you round to the hundredths place or tenths or ones places. I'll just say it's 3 since that's easier.
