Calculator Use

The ratio calculator performs two types of operations:

  • Solve ratios for the missing value when comparing ratios or proportions.
  • Compare ratios and evaluate as true or false to answer whether ratios or fractions are equivalent.

This ratio calculator will accept decimals.

Compare Ratios and Solve for the Missing Value:

Enter A and B to find C and D.
The calculator will simplify the ratio A : B if possible. Otherwise the calculator finds an equivalent ratio by multiplying each of A and B by 2 to create values for C and D.

Enter A, B and C to find D.
The calculator solves for D = C * (B/A)

Enter A, B and D to find C.
The calculator solves for C = D * (A/B)

Evaluate Equivalent Ratios:

Enter A, B, C and D.
Is the ratio A : B equivalent to the ratio C : D? The calculator finds the values of A/B and C/D and compares the results to evaluate whether the statement is true or false.

Convert Ratio to Fraction

A ratio, like a fraction, is a statement of the proportion of two numbers. The ratio 1 : 2 is read as "1 to 2" and is the same as the fraction 1/2. To convert a ratio to a fraction use the first number in the numerator and the second number in the denominator.

1 : 2 = 1/2
