Iloczyn liczb 2 3/4 i 2 1/5 pomniejsz o sumę liczb -3/4 i 0,6 .
2¾*2⅕=¹¹/₄*¹¹/₅=¹²¹/₂₀
-¾+⅗=-¹⁵/₂₀+¹²/₂₀=-³/₂₀
¹²¹/₂₀-(-³/₂₀)=¹²⁴/₂₀=6 ⁴/₂₀=6 ⅕=6,2
Pozdrawiam ;)
Iloczyn liczb 2 3/4 i 2 1/5 pomniejsz o sumę liczb -3/4 i 0,6
2¾ *2⅕ - (-¾ + 0,6) =
= (11/4)*(11/5) - (-¾ + 3/5) =
= (121/20) - ( -15/20 + 12/20) =
= (121/20) - (- 3/20) =
= 121/20 + 3/20 =
= 124/20 =
= 62/10 =
= 6,2
