Question

4/5+х-1/5=2ц 2/5 решите

Comments

с обьяснением

Answer 1

4/5 + x - 1/5 = 2 2/5
3/5 + x  = 12/5
x = 12/5 - 3/5
x = 9/5 = 1 4/5

или
4/5 + x - 1/5 = 2 2/5
8/10 + x - 2/10 = 2 4/10
0.8 + x - 0.2 = 2.4
0.6 + x = 2.4
x = 2.4 - 0.6
x = 1.8

неправильно проверку сделай и увидишь 17/5, а надо 2ц2/5

4/5 + 9/5 - 1/5 = (4+9-1)/5 = 12/5 = 2 2/5
