Question

tình bằng cách thuân tiện nhất

a, 7429 - ( 3125 + 429 )

b, \(\frac{19}{37}+\left(1-\frac{19}{37}\right)\)

Answer 1

a,7429-(3125+429)

=7429-3125-429

=(7429-429)-3125

=7000-3125

=3875

b,\(\frac{19}{37}+\left(1-\frac{19}{37}\right)\)

=\(\frac{19}{37}+1-\frac{19}{37}\)

=\(\frac{19}{37}-\frac{19}{37}+1\)

=\(0+1\)

=\(1\)

Answer 2

a) 7429-(3125+429)=7429-3125-429=7429-429-3125=7000-3125=3875

b) 19/37+(1-19/37)=(19/37-19/37)+1=0+1=1

Answer 3

a) 7429-(3125+429)=7429-3125-429=7429-429-3125=7000-3125=3875

b) 19/37+(1-19/37)=(19/37-19/37)+1=0+1=1

Answer 4

a) 7429-(3125+429)=7429-3125-429=7429-429-3125=7000-3125=3875

b) 19/37+(1-19/37)=(19/37-19/37)+1=0+1=1

Answer 5

\(a\)) \(7429-\left(3125+429\right)\)

\(=7429-3554\)

\(=3875\)

b) \(\frac{19}{37}+\left(1-\frac{19}{37}\right)\)

\(=\frac{19}{37}+1-\frac{19}{37}\)

\(=0+1=1\)

k cho mk nha bn !
