Пошаговое объяснение:

5) 4\frac{5}{7} -x=2\frac{6}{7}

\frac{33}{7} -x=\frac{20}{7}

-x=\frac{33}{7} -\frac{20}{7}

-x=-\frac{13}{7}

x=\frac{13}{7}

6) 4.5×\frac{3}{5} = 2.7

залишилося: 4.5-2.7 = 1.8кг

7) 3.2(x+1.04)=7.36

x+1.04=2.3

x=2.3-1.04

x=1.26

Пошаговое объяснение:

5

4 5/7 - х = 2 6/7

х = 4 5/7 - 2 6/7

х = 3 12/7 - 2 6/7

х = 1 6/7

6

1) 3/5 * 4,5 = 3/5 * 45/10 = 3/1 * 9/10 = 27/10 = 2,7 (кг) - арбуза съели

2) 4,5 - 2,7 = 1,8 (кг) - арбуза осталось

7

3,2 * (х + 1,04) = 7,36

х + 1,04 = 7,36 : 3,2

х + 1,04 = 2,3

х = 2,3 - 1,04

х = 1,26
