- Find the total parts of the ratio: 4 + 5 = 9.
- Divide the value by the total ratio parts: 128 ÷ 9 = 14.22 (rounded to two decimal places).
- Multiply the first part of the ratio by the value from step 2: 4 x 14.22 = 56.88 (rounded to two decimal places).
- Multiply the second part of the ratio by the value from step 2: 5 x 14.22 = 71.1 (rounded to two decimal places).
- Add the result of step 3 and step 4 together: 56.88 + 71.1 = 127.98 (rounded to two decimal places).
