a) 20/11x33/23x69/180=20/11x11x3/23x23x3/20x9=9 ( 11x3=33 23x3=69 20x9=180 )
b)(675,98+888,66+111,34)x0,01
=(675,98+1000)x0,01
=1675,98x1/100
=16,7598
b) = ( 675,98 x 0,01 ) + ( 888,66 + 111,34 ) x 0,01
= 6,7598 + 10
= 16,7598
\(a:\frac{20}{11}\cdot\frac{33}{23}\cdot\frac{69}{180}=\frac{20\cdot33\cdot69}{11\cdot23\cdot180}=\frac{9}{9}=1\)
b: (675,98 + 888,66 + 111,34) x 0,01
= (675,98 + [888,66 + 111,34]) x 0,01
= (675,98 + 1000) x 0,01
= 1675,98 x 0,01
= 16,7598
\(\frac{20}{11}\times\frac{33}{23}\times\frac{69}{180}=\frac{20}{11}\times\left(\frac{33}{23}\times\frac{23}{60}\right)\)
=\(\frac{20}{11}\times\frac{759}{1380}=\frac{20}{11}\times\frac{11}{20}=\frac{220}{220}=1\)
\(\frac{20}{11}\times\frac{33}{23}\times\frac{69}{180}=\frac{20}{11}\times\left(\frac{33}{23}\times\frac{23}{60}\right)\)
\(=\frac{20}{11}\times\frac{759}{1380}=\frac{20}{11}\times\frac{11}{20}=\frac{220}{220}=1\)
$\frac{20}{11}\times \frac{33}{23}\times \frac{69}{180}=\frac{20}{11}\times \left(\frac{33}{23}\times \frac{23}{60}\right)$
a 20/11x33/23x23/90=20/11x33/90=20/11x11/30=20/30=2/3
b =6,7598+8,8866+1,1134=6,7598+10=16,7598
a) \(\frac{20}{11}\) x \(\frac{33}{33}\) x \(\frac{69}{180}\)
=( \(\frac{20}{11}\) x 1) x \(\frac{69}{180}\)
= \(\frac{20}{11}\) x \(\frac{69}{180}\)
= \(\frac{2}{3}\)
b) (675,98 + 888,66 + 111,34) x 0,01
= 1675,98 x 0,01
= 16,7598
a)
\(\frac{20}{11}.\frac{33}{23}.\frac{69}{180}\)
\(=\left(\frac{20}{11}.\frac{69}{180}\right).\frac{33}{23}\)
\(=\frac{23}{33}.\frac{33}{23}=1\)
b) 0,8 x 96 + 0,8 x 2 x 2
=0,8 x ( 96+2+2)
=0,8 x 100
= 80
a) 20/11 x 33/23 x 69/180 = 60/23 x 69/180 = 1
b) 0,8 x 96 + 0,8 x 2 x 2 = 0,8 x ( 96 + 2 ) x 2 = 0,8 x 98 x 2 = 78,4 x 2 = 156,8
