\(340-\left(200+40\right)\)
\(=340-200-40\)
\(=300-200\)
\(=100\)
\(150:\left(20+5\right)\)
\(=150:25\)
\(=6\)
\(340-\left(200+40\right)\)
\(=340-240\)
\(=580\)
\(150:\left(25+5\right)\)
\(=150:30\)
\(=50\)
340 - (200 + 40) = 340 - 240 = 100
150 : (20 + 5) = 150 : 25 = 6
340-(200+400)=340-240=100
150:(20+5)=150:25=6
\(340-\left(200+40\right)=340-240=100\)
\(150:\left(20+5\right)=150:25=6\)
340-(200+40)= 340 - 240 = 100
150:(20+5)= 150 :25 = 6
( bài này nhẩm cũng ra á :))
340 - (200 + 40) 150 : (20 + 5)
= 340 - 240 = 150 : 25
= 100 = 6
