Question

1+³/₇:¹/₂=

(0,6+0,9) :3 =

10* (0,5 +¹/₄=

0,3+0,5 *4=

¹/₂+¾-0,5*0,75=

Answer 1

1+³/₇:¹/₂=

= 1 + (3/7) *(2/1 )=

= 1 + 6/7 =

= 1 i 6/7

 

(0,6+0,9) :3 =

= 1,5 : 5=

= 0,5

 

10* (0,5 +¹/₄)=

= 10*(1/2 + 1/4) =

= 10*(2/4 +1/4) =

= 10* (3/4) =

=  30/4 =

= 7 i 2/4 =

= 7 i 1/2

 

0,3+0,5 *4=

= 0,3*2 =

= 0,6

 

¹/₂+¾-0,5*0,75=

=2/4 + 3/4 - (1/2)*(3/4) =

= 5/4 - 3/8 =

= 10/8 -3/8 =

= 7/8

Answer 2

1+³/₇ *²/¹ = 1⁶/₇

15/10*1/3=1/2

10*0,75=7,5

0,3+2=2,3

0,5+0,75-0,375=1,25-0,375=0,875
