For a pile of chemical fertilizer, 360 tons are transported in the first day, accounting for 2 / 5 of this pile of chemical fertilizer. The ratio of tons transported in the second day to the total tons of this pile of chemical fertilizer is 1:5 How many tons were shipped the next day?
360 △ 2 / 5 × 1 / 5 = 180 tons
For a pile of chemical fertilizer, 120 tons are transported in the first day, which accounts for 25% of the total. The ratio of the tons transported in the second day to the total tons of the pile of chemical fertilizer is 1:5. How many tons are transported in the second day?
120 △ 25 × 15, = 120 × 52 × 15, = 60 tons; answer: 60 tons will be transported the next day
