3. In the donation activities, Xiaogang donated one fifth of his own money, and Xiaoqiang donated two thirds of his own money. Who donated more, Xiaogang or Xiaoqiang?
4. Calculate a + 4.7 + A * 6.3-a
5. Solving equation 7a + 3 * 4 = 12a-6

1. Divide 432 by 7, and the remainder is the number to be subtracted
2. 2 + 4 / 7 = 18 / 7.5 = 35 / 7, 1 = 7 / 7. Calculate the rest by yourself
3. It's hard to say who has more. If Xiaogang has 10000 yuan and Xiaoqiang has 1 yuan, Xiaogang has more; if not, Xiaoqiang has more
4、a+4.7+a*6.3-a=a*6.3+4.7
5、7a+3*4=12a-6；5a=18；a=18/5
