a) \(12,045-\left(8,95+4,5\right)x0,1\)
\(=12,045-13,45x0,1\)
\(=12,045-1,345\)
\(=10,7\)
b) \(125,18-115,2:1,2+1,2\)
\(=125,18-96+1,2\)
\(=30,38\)
a) 12,045 – ( 8,95+ 4,5 ) x 0,1
= 12,045 - 40,275 x 0,1
= 12,045 - 4,0275
= 8,0175
b) 125,18 –115,2 : 1,2 + 1,2
= 125,18 - 96 + 1,2
= 29,18 + 1,2
= 30,38
Học tốt
a) 12,045 – ( 8,95+ 4,5 ) x 0,1
= 12,045 - 13,45 x 0,1
= 12,045 - 1,345
= 10,7
b) 125,18 –115,2 : 1,2 + 1,2
= 125,18 - 96 + 1,2
= 29,18 + 1,2
= 30,38
Trả lời:
\(a,\)\(12,045-\left(8,95+4,5\right)\times0,1\)
\(=12,045-13,45\times0,1\)
\(=12,045-1,345\)
\(=10,7\)
\(b,\)\(125,18-115,2\div1,2+1,2\)
\(=125,18-96+1,2\)
\(=29,18+1,2\)
\(=30,38\)
Hok tốt!
Good girl
nhầm
a) 12,045 – ( 8,95+ 4,5 ) x 0,1
= 12,045 - 13,45 x 0,1
= 12,045 - 1,345
= 10,7
a)12,045 - (8,95 + 4,5) x 0,1 = 12,045 - 0,895 - 0,45 = 10,7
b)125,18 - 115,2 : 1,2 +1,2 = 125,18 - 96 + 1,2 = 30,38
