If you put 140 rail of water in a glass, how much concentrate should be added?
Lemon Squash;
1 part concentrate
to 2 parts water

70ml

Step-by-step explanation:

Key:

1.concentrate - c

2.water - w

if 2w   = 1 c

140w = 140w x 1c

                   2w

=70c

= 70 ml of concentrate.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
