Carry out this task

  1. Open the linked tool and enter the displayed values.
  2. Use nine as water parts per one concentrate part.
  3. Choose Calculate & Save and compare the displayed result with the worked calculation.

Calculation and observed tool result

Concentrate = 270 ÷ 9 = 30 ml; finished volume = 300 ml. Only dilute products whose instructions allow it.

Recorded quantity: 300 ml.

What the result means

Thirty millilitres concentrate in 300 ml total is ten percent by additive volume.

A mistake to avoid

Using ratio ten would make the concentrate fraction one eleventh.
