Answer: 10 : 4 : 3
Step-by-step explanation:
According to the question,
For a medicine,
Water used = 1 liter = 1000 ml
Sucrose used = 400 ml
And, Saline used = 300 ml
Thus, the ratio of water, sucrose and saline water for making a medicine,
= 1000 : 400 : 300
= 10 : 4 : 3
Which is the required simplest form of the ratio of water, sucrose and saline water.

For this case, the first thing we must do is define a variable.
We have then:
x: number of initial cards.
We write now the equation that represents the problem:
x - (4) * (6) = 54
From here, we clear the value of x:
x = (4) * (6) + 54
Rewriting:
x = 24 + 54
x = 78
Answer:
The number of cards that william has initially is 78. Lack of information to know how many cards his friends have.
Answer:
(12 ÷ 4) × (18 ÷ 6)
Step-by-step explanation:
(12 ÷ 4) × (18 ÷ 6)
If we solve this or simply this, we would get 9 as our result.
Let's solve and see. Mind you, we've used each of the given numbers just once in the expression.
Thus:
(12 ÷ 4) × (18 ÷ 6)
Solve the parentheses first
3 × 3 = 9.
Therefore,
(12 ÷ 4) × (18 ÷ 6) = 9
