116.67 mm\text{116.67 mm}

Calculate the mean monthly rainfall for the year.

  1. Sum all the monthly rainfall values.

    Total rainfall=45+55+120+210+180+95+70+85+110+160+190+75\text{Total rainfall} = 45 + 55 + 120 + 210 + 180 + 95 + 70 + 85 + 110 + 160 + 190 + 75 Total rainfall=1400 mm\text{Total rainfall} = 1400 \text{ mm}

  2. Divide the total rainfall by the number of months (12).

    Mean monthly rainfall=Total rainfallNumber of months\text{Mean monthly rainfall} = \frac{\text{Total rainfall}}{\text{Number of months}} Mean monthly rainfall=1400 mm12\text{Mean monthly rainfall} = \frac{1400 \text{ mm}}{12} Mean monthly rainfall=116.67 mm\text{Mean monthly rainfall} = 116.67 \text{ mm}

    The mean monthly rainfall for the year is 116.67 mm\boxed{\text{116.67 mm}}.
