The weight of Tyler's coin is correctly represented by options A (0.231) and C (2/10+3/100+1/1000), both equating to two hundred thirty-one thousandths of an ounce.
The weight of Tyler's coin is two hundred thirty-one thousandths of an ounce.
Let's identify which expressions correctly represent this weight.
A. 0.231 - Correct, because this is the decimal form of two hundred thirty-one thousandths.
B. 2.31 - Incorrect, this represents two and thirty-one hundredths, which is ten times greater than the weight of the coin.
C. 2/10+3/100+1/1000 - Correct, as this sums to 0.231 when the fractions are added.
D. 2+3/10+1/100 - Incorrect, this sum is much larger than the weight of the coin and represents two and three tenths plus one hundredth.
E. 2/1000+3/1000+1/1000 - Incorrect, the sums of these thousandths are only six thousandths, which is a smaller value than needed.
F. 231 - Incorrect, this is just an integer and does not represent a fraction of an ounce.
Thus, the correct representations for the weight of the coin are given by options A and C.
