Column () 6 meters long wire, with 2/3, how many meters? Column type () II. A fair judgment. 5 points 1, the reciprocal of a number is less than itself, and this number must be a false score. () 2, 1 kg of sugar, ate 1/2, and left 1/2 kg. () 3. A number that is not 0 times the true fraction, and the product must be less than this number. () 4. Poplar is more than willow 1/5, then willow is less than poplar 1/5()5, a×4/5 =b× 2/3, then a < B () Third, merit-based admission. 10 min 1, a bag of rice is eaten by 3/8, and the number of "1" is () ① leftover rice ② leftover rice ③ a bag of rice ② the product of two true points must be () ① natural number ② false points ③ true points ③ a wire 12m, and it is necessary to install electric lights. And () the true score of 14m211m3 is 4, a×1/3 = b×14/3 = c×1/5 (a, b and c are not 0), among the three numbers. 1A2B3C5, Uncle Wang has 2 more geese than 4/5 chickens. If he has 25 chickens, then he has () geese. 1222 18364, clever calculation 1, The direct write number is 4/15× 3/53/8× 43/2× 2/33× 5/713×12× 4/14× 8/. How much is 2/5 of kloc-0//20+1/30+1/42+1/56 = 4. ③105 less than 5/7? V. Migration ability: 30 points 1. Xiaoming has 60 stamps, Xiaohong has more than Xiaoming 1/5, and Xiaoming has fewer than Xiaohong. 2. The fuel consumption of a car 1 km is 3/8 kg. According to this calculation, how many kilograms of fuel will be consumed for 56 kilometers? How many kilometers is it feasible to consume 84 kilograms of fuel? 3. There are more vegetables from North Sacido than radishes 1/3. It is known that radishes shipped from the north are less than vegetables. 4. Hualian Supermarket delivered 45 boxes of apples, which were sold 1/3 on the first day, and the remaining 2/5 were sold out the next day. How many boxes of apples were sold the next day? To build a 600-meter-long expressway, 250 meters have been built. Only two thirds of this highway has been completed. How many more meters will be built?
