Answer:
2. power
4. tenth
20. hundred-thousandth
40. 5.063
50. 67/10
Step-by-step explanation:
20. If the underlined digit is the zero, the answer is "hundred-thousandth." It's hard to tell from the picture if zero is the underlined digit.
40. 5 and 63/1000 = 5 + 63/1000 = 5 + 0.063 = 5.063
50. 6.700 = 6700/1000 = 67/10
