CALC 1 Ratios Calculator
This calculator features ratios calculations, A/B = C/D, along with basic calculator functions.
Many math and financial problems can be expressed as ratios. This calculator makes these calculations easier since you see the values on the key previews.
This calculator will calculate the A, B, C or D values base on the other 3 values.
Example:
A roll of 12-2 wire costs $114 for a 250 foot roll, and $69 for a 50 foot roll. How much can you save by buying the larger roll?
| Value | Keystrokes | Display | Description |
|---|---|---|---|
| shift C ABCD | 0 | Clears the A, B, C, D values, B and D are set = 1. | |
| 69 | A | 69.00 | Stores 50 foot roll price as the A value. |
| 50 | B | 50.00 | Stores the length of the 50 ft roll as the B value. |
| 250 | D | 250.00 | Stores the length of the 250 ft roll as the D value. |
| C | 345.00 | Calculates how much 250 feet of wire would cost if purchased as 50 foot rolls | |
| -114= | 231.00 | Calculates the potential savings by buying the 250 foot roll instead of separate 50 foot rolls. |
The Ratios calculator allows you to change individual values to calculate ratios. In this example you could enter 114 as value C, then calculate the price of a 50 foot roll at the 250 foot price/foot to determine the premium you are paying for the smaller roll.
