b.7/16+(6/15+25/16)

ai giai xong nho bao cho minh de minh con tick nha

Answer 1

a. 36,84+38,59+63,16

= (36,84 + 63,16) + 38,59

= 100 + 38,59

= 138,59

b.7/16+(6/15+25/16)

= (7/16 + 25/16) + 6/15

= 2 + 6/15

= 12/5

  

Answer 2

giai giup minh voi

Answer 3

a)36,84+38,59+63,16

=(36,84+63,16)+38,59

=100+38,59

=138,59

b)7/16+(6/15+25/16)

=7/16+25/16+6/15

=22/16+6/15

=71/40

Answer 4

a) 36,84 + 38,59 + 63,16 

= ( 36,84 + 63,16 ) + 38,59 

= 100 + 38,59

= 138,59

b) \(\frac{7}{16}\)+(\(\frac{6}{15}\)+ \(\frac{25}{16}\)) 

= ( \(\frac{7}{16}\) + \(\frac{25}{16}\)) + \(\frac{6}{15}\) 

=  \(\frac{32}{16}\)+ \(\frac{6}{15}\)

= 2 + \(\frac{6}{15}\)

= \(2\frac{6}{15}\)

Answer 5

a) 36,84 +38,59 + 63,16 =( 36,84 + 63,16) + 38,59

                                     =100 + 38,59

                                      = 138,59

b) 7/16 +( 6/15 + 25/16) = 6/15 + ( 7/16 + 25/16) 

                                    =6/15 + 2

                                     = 36/15

                           k cho mk nha ! ^_^
