k cho mik nha

a ) 0,783 : 87 = 0,009
86,76 : 12 = 7,23
266,22 : 34 = 7,83
483 : 35 = 13,8
b ) 127 : 25,4 = 5
26,52 : 3,9 = 6,8
19,04 : 5,6 = 3,4
270: 10,8 = 25

a) 5,6 x 4 + 5,6 x 3 + 5,6 x 2 + 5,6
=\(5,6.\left(4+3+2+1\right)\)
\(=5,6.10\)
\(=56\)
b) 7,89 x 54 - 7,89 x 52 - 7,89
=\(7,89.\left(54-52-1\right)\)
\(=7,89.1\)
\(=7,89\)
CHÚc bạn học tốt

\(5,6\cdot7,5-5,6\cdot4,5+5,6-3\cdot5,6\)
\(=5,6\left(7,5-5,6+1-3\right)\)
\(=5,6\cdot\left(-0,1\right)\)
\(=-0,56\)

\(0,336\times X:0,35=0,6\)
\(\Rightarrow0,336\times X=0,6\times0,35\)
\(\Rightarrow0,336\times X=0,21\)
\(\Rightarrow X=0,336:0,21\)
\(\Rightarrow X=1,6\)
\(5,6\times4+5,6\times3+5,6\times2+5,6\)
\(=5,6\times4+5,6\times3+5,6\times2+5,6\times1\)
\(=5,6\times\left(4+3+2+1\right)\)
\(=5,6\times10=56\)
X : 5,6 = 19,04
X = 19,04 x 5,6
X = 106,624
x=19.04 x 5.6
x=106.624
