- The ratio of rice to water is 1 to 2.5
- The ratio of water to rice is 2.5 to 1
Ratios are used to compare quantities of different measurements
The entries on the table are given as:
<u>Rice Water</u>
2 5
3 7.5
5 12.5
8 20
<h3>The ratios of both quantities</h3>The ratio (r) of rice and water is then calculated as:
Pick any corresponding table entry.
So, we have:
Divide
This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1

Equation:
Solve for n: n = 112
Step-by-step explanation:
To first set up the equation, you need to look at the verbal description and translate into numbers and operations:
'three fourths a number' =
'plus 8' = + 8
'is' =
'20 less' = - 20
'the number' = n
Put the expressions together:
'three fourths a number plus 8':
'20 less than the number': n - 20
Set them equal to each other and solve:
Add 20 to both sides:
Subtract from both sides:
Multiply both sides by :
Solve for n: n = 112
