Question

Вычисли удобным способом: 90: (5•2)=__________________________ 150: (6•5) =__________________________ 600 : (50 •2) =__________________________ 84: (2•6) =__________________________ 210: (7•6) =__________________________ 400: (10•8) =__________________________

Answer 1

90:10=9.150:30=5.600:100=6.84:12=7.210:42=5.400:80=5

Answer 2

90:10=9
150:30=5
600:100=6
84:2=42:6=7
210:7=30:6=5
400:10=40:8=5

Answer 3

90: (5•2) = 90: 10 = 9

150: (6•5) = 150: 30 = 5

600: (50+•2) = 600: 52 = 11.538461538461538

84: (2•6) = 84: 12 = 7

210: (7•6) = 210: 42 = 5

400: (10•8) = 400: 80 = 5

The results of the calculations are as follows: - 90: (5•2) = 9 - 150: (6•5) = 5 - 600: (50+•2) = 11.538461538461538 - 84: (2•6) = 7 - 210: (7•6) = 5 - 400: (10•8) = 5

Please note that I have used the division operation to perform the calculations. If you would like to use a different method or have any specific requirements, please let me know.
