1.Виконайте множення дробів:
1,3 : 7 = 0,1857 (округлено до 4 знаків після коми)
13,01 : 0,2 = 65,05
0,16 - 0,35 = -0,19
0,0002 - 0,04 = -0,0398 (округлено до 4 знаків після коми)
13,5 - 0,01 = 13,49
113,24 : 1000 = 0,11324

2.Виконайте ділення дробів:
3,6 : 0,03 = 120
6,944 : 3,2 = 2,17 (округлено до 2 знаків після коми)
117.201 : 100 = 1172,01 (округлено до 2 знаків після коми)

3.Округліть дроби до десятих:
112,318 = 112,3
206,86905 = 206,9

4.Розвʼязати рівняння:
x : 1,04 - 4,1 = (x/1,04) - 4,1 (перенесемо 1,04 на ліву сторону)
(x/1,04) - 4,1 = 0 (додаємо 4,1 до обох сторін)
x/1,04 = 4,1
x = 4,1 * 1,04 = 4,264 (округлено до 3 знаків після коми)
x * 0,23 = 11,5 (перенесемо 0,23 на праву сторону)
x = 11,5 / 0,23 = 50 (округлено до цілого)

5.Розв'язати задачу:
Ціна 1 кг яблук = 51,6 / 3 = 17,2 грн. (округлено до 1 знаку після коми)
