4,25.58,47-125+41,53.4,25
= 4,25.58,47+41,53.4,25-125
= 4,25.(58,47+41,53)-125
= 425-125
= 300
4,25.58,47-125+41,53.4,25
=4,25.(58,47+41,53)-125
=4,25.100-125
=425-125=300
a) 125.3 + 125. 64 - 125
= 125 . ( 3 + 64 - 1 )
= 125 .66
= 8250
b) 125.3 + 125.64 + 125
= 125.( 3 + 64 + 1 )
= 125.68
= 8500
\(125\times2+125\times9-125\)
\(=125\times\left(2+9-1\right)\)
\(=125\times10\)
\(=1250\)
125 * 2 + 125 * 9 - 125
125 * ( 2 + 9 -1)
125 *10
1250
a) (4+4)x(2019 +2019 +.....+2019)
= 8 x 125 x 2019
= (8 x 125) x 2019
= 1000 x 2019
= 2019000
b) ( 42+42+...+42)+(125+125+....+125)
= 42 x 125 + 58 x 125
= 125 x ( 42 + 58)
= 125 x 100
= 12500
42+42+...+42)+(125+125+....+125)
= 42 x 125 + 58 x 125
= 125 x ( 42 + 58)
= 125 x 100
= 12500
4,25.58/47-125+41,53.4,25
=4,25(58,47-41,53)+125
=4,25.16,94+125
=71,995+125
=196,995
4,25.58,47-125+41,53.4,25=196,995
