Question

3. If a : b = 3 : 8, find the value of 4a+3b ÷ 6a-b

​

Answer 1

Answer:

Step-by-step explanation:

18/5

Step-by-step explanation:

a:b = 3:8

i.e,

a = 3x & b = 8x

hence,

4a+3b     =    4*(3x) + 3*(8x)

6a-b               6*(3x) - 8x

               

              =     12x +24x      = 18

                      18x - 8x        = 5

= 18.5 or 18/5
