ratio of the number of a lemon to the number of glass of water in the bottle of lemon juice is 2.5 how much glass of water will be mix with 12 11
Answers
Answer:
Ratio of Lemon to water=3:5
Number of lemons =12
3 parts of lemon =12
∴1 part of lemon ≡
3
12
=4
∴5 part of water ≡4×5=20
∴ number of cups of water to be used=20

Answer :
›»› 20 glass of of water will be mix with 12 lemons.
Given :
- Ratio of the number of a lemon to the number of glass of water in the bottle of lemon juice is 2:5.
To Find :
- How much glass of water will be mix with 12.
Solution :
→ Lemon = 12
→ Lemon : Water = 2 : 5
→ Lemon/Water = 2/5
Let us assume that, the "x" galas of water will be mix with 12.
→ 12/Water = 2/5
We can write,
→ 12/x = 2/5
Cross multiply,
→ 12 * 5 = 2 * x
Multiply 12 and 5,
→ 60 = 2 * x
Multiply 2 and x,
→ 60 = 2x
Move the variable to left-hand side and change the symbol,
→ 60 - 2x = 0
Move the constant to right side and change the sign,
→ -2x = -60
Change the sign of both sides of the equation,
→ 2x = 60
Divide both sides by the same number,
→ x = 30
Hence, 20 glass of of water will be mix with 12 lemons.
Verification :
→ 12/Water = 2/5
→ 12/30 = 2/5
→ 6/15 = 2/5
→ 2/5 = 3/5
→ 2 * 5 = 2 * 5
→ 10 = 10
Here, LHS = RHS
