1. To write 3/8 as a decimal, divide the numerator (3) by the denominator (8). The answer is 0.375. So, the correct answer is B. 0.375.
2. To determine which fraction is also a repeating decimal, you need to look for fractions where the denominator is not a power of 2 or 5. In this case, the only fraction that fits this criterion is A. 7/14, which is equivalent to 1/2.
3. To write 3/20 as a decimal, divide the numerator (3) by the denominator (20). The answer is 0.15. So, the correct answer is A. 0.15.
4. To order the set of numbers from least to greatest, you can convert the fractions to decimals. In this case, the decimals are: 3/5 = 0.6, 17/20 = 0.85. The set of numbers in order from least to greatest is 0.49, 0.5, 3/5, 17/20. So, the correct answer is B. 0.49, 0.5, 3/5, 17/20.
5. To determine who ate the most pizza, compare the decimal values of the amounts eaten by each friend. The largest decimal value is 0.2, which corresponds to Jessica. So, the correct answer is D. Jessica.
