2 2/7 = 2 x 7 + 2 = 16/7
4 1/2 = 4 x 2 + 1 = 9/2
     16x2= 32     9x7= 63
       7x2= 14     2x7= 14
32+63= 95; 95/14
 
so, it's 95/14 or 6 4/5

Two containers, A and B begin with equal volumes of liquid.
Reika [66]

Answer:

volume left in A is 80ml

Step-by-step explanation:

let original volume in both be x ml

after pouring from A to B

vol in A = x - 120

vol in B = x + 120

now it is given that

vol in B = 4 times vol in A

implies

x + 120 = 4 \times (x - 120) \\ x + 120 = 4x - 480 \\ 3x = 600 \\ x = 200

hence original volume in A is 200ml. after pouring in B it is 200-120 = 80 ml
