Question

Given A= 15/6

, B = 52/16

and C =
105/26

then find:-
(a) A ÷ B
(b) A + B-C​​

Answer 1

Step-by-step explanation:

A= 15/6

B= 52/16

C= 105/26

a) A/B

= (15/6)/(52/16)

= 15/6*16/52

= 240/312

= 30/39

b) A+B-C

= 15/6+52/16-105/26

= 1065/624

= 355/208

Answer 2

Answer:

( a ) 5 / 8 ( or ) 0.625

( b ) 32 / 13

Step-by-step explanation:

A = 15 / 6

  = ( 15 / 3 ) / ( 6 / 3 )

A = 5 / 2

B = 52 / 16

  = ( 52 / 16 ) / ( 16 / 16 )

  = 4 / 1

B = 4

C = 105 / 26

( a ) A ÷ B

= A / B

= ( 5 / 2 ) / 4

= 5 / ( 2 x 4 )

= 5 / 8

 ( or )

= 0.625

( b ) A + B - C

= ( 5 / 2 ) + 4 - ( 105 / 26 )

= 2.5 + 4 - ( 105 / 26 )

= 6.5 - ( 105 / 26 )

= [ ( 6.5 x 26 ) / 26 ] - ( 105 / 26 )

= ( 169 / 26 ) - ( 105 / 26 )

= ( 169 - 105 ) / 26

= 64 / 26

= ( 64 / 2 ) / ( 26 / 2 )

= 32 / 13
