Question

0,17 x 250 + 63 x 1,7 - 87 x 1,7

Answer 1

0,17 x 250 + 63 x 1,7 - 87 x 1,7

=1,7x25+ 63 x 1,7 - 87 x 1,7

=1,7x(25+63-87)

=1,7x1

=1,7

Answer 2

\(0,17\times250+63\times1,7-87\times1,7\)
\(=0,17\times10\times25+63\times1,7-87\times1,7\)
\(=1,7\times25+63\times1,7-87\times1,7\)
\(=1,7\times\left(25+63-87\right)\)
\(=1,7\times1\)
\(=1,7\)

Answer 3

\(0,17\times250+63\times1,7-87\times1,7\\ =1,7\times25+63\times1,7-87\times1,7\\ =1,7\times\left(25+63-87\right)\\ =1,7\times1\\ =1,7\)

Answer 4

`=0,17xx10xx25+63xx1,7-87xx1,7`

`=1,7xx25+63xx1,7-87xx1,7`

`=1,7xx(25+63-87)`

`=1,7xx1`

`=1,7`

Answer 5

0,17x250+63x1,7-87x1,7

=1,7x25+63x1,7-87x1,7

=1,7x(25+63-87)

=1,7x1

=1,7
