Question

поставь скобки чтоб равенства стали верными: 140-80/4*5=75 140-80/4*5=600 140-80/4*5=136 8*30-30/3*5=238 8*30-30/3*5=0 8*30-30/3*5=350

Answer 1

$((140 - 80) \div 4) \times 5 = 75 \\ (140 - (80 \div4)) \times 5 = 600 \\ 140 - (80 \div (4 \times 5)) = 136 \\ (8 \times 30) - (30 \div (3 \times 5)) = 238 \\ 8 \times (30 - 30) \div (3 \times 5) = 0 \\ ((8 \times 30 - 30) \div 3) \times 5 = 350$
