Divide the 5-meter-long rope into 3 parts, each part is 1 / 3 of the total length, and each part is 5 / 3 of the length
A rope is 5 meters long, divided into 8 parts on average, each of which is long______ Meters, each of which accounts for 50% of the total length______ ．
1 △ 8 = 18; 5 × 18 = 58 (m); answer: each piece is 58 m long, accounting for 18% of the total length
Xiaolan measured the floor plan of her house 14 cm in length and 9 cm in width on the house design drawing with a scale of 1%. Xiaolan's father is going to put 0.6 meter square tiles on the floor of her house. How many such tiles do she need?
The actual length of the house is 14m and the width is 9m. The total area is 14 * 9 = 126 m2. Another 126 / 0.6 = 210 (blocks) needs 210
