49 and 25 / 25 times minus 5
There's another way I don't know if it's OK, that is, first multiply 49 and - 5, then + 24 / 25 times - 5

49 and 24 out of 25 equals 50-1 out of 25, (50-1 out of 25) times - 5, equals - 250 plus 1 out of 5, and finally equals - 249 and 4 out of 5

3.38-4,3 + 2.22-25% (mathematical calculation, simple calculation)

According to the law of exchange and the law of association, there are:
3.38－3/4＋2.22－25%
＝(3.38＋2.22)－(3/4＋25%)
＝5.6－(0.75＋0.25)
＝5.6－1
＝4.6
