The total amount of snowfall on the two days combined is 4 3/8 cm

<h3>Addition of fractions </h3>

From the question, we are to determine the amount of snowfall on the two days combined

From the given information,

the amount of snowfall was 1/8 cm on Thursday

The amount of snowfall was 4 1/4 cm on Wednesday

Then,

The total amount of snowfall on the two days combined will be

$\frac{1}{8}+4\frac{1}{4}$ cm

= $\frac{1}{8}+\frac{17}{4}$

= $\frac{1+34}{8}$

= $\frac{35}{8}$

= $4\frac{3}{8} \ cm$

Hence, the total amount of snowfall on the two days combined is 4 3/8 cm
