Question

a) -3/8 . 2/5 + -3/8 . 14/5

b) 3/2 . 7/2 + (-5/6 + 1/10) : 11/30

* Hép mi *

Answer 1

a)\(\frac{-3}{8}.\frac{2}{5}+\frac{-3}{8}.\frac{14}{5}\)

\(=\frac{-3}{8}.\left(\frac{2}{5}+\frac{14}{5}\right)\)

\(=\frac{-3}{8}.\frac{16}{5}\)

\(=\frac{-6}{5}\)

Answer 2

a, =-3/8.(2/5+14/5)

    =-3/8.16/5

   =-6/5

b, =3/2.7/2+-11/15:11/30

    =21/4+-2

    =13/4

Answer 3

a,\(=\frac{-3}{8}\left(\frac{2}{5}+\frac{14}{5}\right)=\frac{-3}{8}.\frac{16}{5}=\frac{-6}{5}.\)

Answer 4

a)     -3/8 . 2/5 + -3/8 .14/25 

      =  -3/8 .( 2/5 +14/25 )

       =  -3/8 .   24/25

        =  -9/25

b)3/2 . 7/2 + ( -5/6 + 1/10  )  :  11/30

= 21 /  4 + - 44 / 60 : 11/30

=21  / 4+ -2

= -13 /4
