Answer:
1. 20 by 6
2. 20 by 8
3. 6 by 10
4. 6 by 40
Step-by-step explanation:
just do 2/3 of each number then that is the new number.
1/3 of 30 is 10, so 2/3 is 20.
and so on
Answer:
1, 2, and 5
Step-by-step explanation:

<h3>How to solve variation ?</h3>
y, varies directly as x. Therefore,
y ∝ x
Therefore,
y = kx
where
- k =constant of proportionality
Therefore,
10 = 6k
k = 10 / 6
k = 5 / 3
Hence, when y = 14
y = kx
14 = 5 / 3 x
cross multiply
42 = 5x
x = 42 / 5
x = 8.4
