Question

1/2*1/3+3/10=

14/8:7/3-3/8:9/5=

Answer 1

1/2 * 1/3 + 3/10

= ( 1/2 * 1/3 ) + 3/10

= 1/6 + 3/10 

= 7/15

14/8 : 7/3 - 3/8 : 9/5

= ( 14/8 : 7/3 ) - ( 3/8 : 9/5 )

= ( 14/8 * 3/7 ) - ( 3/8 * 5/9 )

= 3/4       -         5/24

= 13/24

Answer 2

1/2*1/3+3/10=1/6+3/10

                     =28/60

14/8:7/3-3/8:9/5=14/8*3/7-3/8*5/9

                          =42/56-15/72

                          =13/24

Answer 3

1/6 + 3/10 =

= 10/60 + 18/60

=28/60

=7/15

14/8 : 7/3 - 3/8 : 9/5 =

=14/8 x 3/7 - 3/8 x 5/9

=3/4 - 5/24

=18/24 - 5/24

=13/24

Answer 4

1/2 x 1/3 + 3/10

= 1/6 + 3/10

= 5/30 + 9/30

= 14/30

= 7/15

14/8 : 7/3 - 3/8 : 9/5

= 14/8 x 3/7 - 3/8 x 5/9

= 42/56 - 15/72

= 3/4 - 5/24

= 18/24 - 5/24

= 13/24

Answer 7

1/2 * 1/3 + 3/10

= ( 1/2 * 1/3 ) + 3/10

= 1/6 + 3/10 

= 7/15

14/8 : 7/3 - 3/8 : 9/5

= ( 14/8 : 7/3 ) - ( 3/8 : 9/5 )

= ( 14/8 * 3/7 ) - ( 3/8 * 5/9 )

= 3/4       -         5/24

= 13/24
