1. Сложение десятичных дробей
1) $$0,053692 + 8,4351 = 8,488792$$
2) $$7,454 + 0,09633 = 7,55033$$
3) $$0,99073 + 0,00927 = 1,00000$$
4) $$1,5561 + 4,7439 = 6,3000$$
5) $$1,2132 + 28 = 29,2132$$
6) $$86,235 + 53,816 = 140,051$$
7) $$0,012818 + 0,045182 = 0,058000$$
8) $$0,0314 + 96 = 96,0314$$
9) $$3,648 + 33,208 = 36,856$$
10) $$5,876 + 2,124 = 8,000$$
2. Вычитание десятичных дробей
1) $$1,41 - 0,29373 = 1,11627$$
