Answer: He'd have to work 15 days.
Step-by-step explanation
With the money in his bank account he'd have to get $173 to be able to pay for the rest of the board. If you were to divide 173 by 12 you'd get 14.4166666667. But you can't have a decimal so you'd round up to get a total of 180. Which is how you get the answer of him needing to work for 15 days.
Hello!
----------
I think that 12/42=10/35 is a true proportion. 10/9=11/10 are almost a true proportion, but 10/9 is 1.1111111111..., and 11/10 is 1.1. 48/56=40/48 and 1/2=3/4 are different numbers when in decimal form.

I hope this helps and have a great day! :)
Answer:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
