There are 630kg apples in the fruit shop. One third of them are sold on the first day, and four ninth of them are sold on the second day. How many kg more are sold on the second day than on the first day?

630 × (4 / 9-1 / 3) = 70kg
A: the second day sold 70 kg more than the first day

Let 2a-3b = 0, then ab=______ ，a−bb=______ ．

It is known that a total of 110 people from unit a and B visit a park. The price of park tickets is as follows: the number of people (person) is 1-50 51-100 100, and the ticket price (yuan / person) is 12108 (1). When the number of people in two units is the same, do you think it is cost-effective for the two units to buy tickets separately or together? Why? (2) When there are less than 50 people in unit a, if the two units purchase tickets separately, then the two units need to pay a total of 1190 yuan?

(1) When the number of people in two units is the same, there are 55 people in each unit. If two units buy tickets separately, each unit needs to pay 55 × 10 = 550 yuan, and the two units need to pay a total of 1100 yuan. If two units buy tickets together, then the two units need to pay 110 × 8 = 880 yuan If the number of people in unit B is less than 50, the number of people in unit B must be more than 50. If the number of people in unit a is x, then the number of people in unit B is (110-x). ① when the number of people in unit a is less than 50, and the number of people in unit B is 51-100, the meaning of the question is: 12x + 10 (110-x) = 1190, and the solution is: x = 45, at this time, (110-x) = 65; ② when the number of people in unit a is less than 50, the meaning of the question is: 12x + 8 (110-x) = 1190, and the solution is: X =So there are 45 people in unit a and 65 people in unit B
