Answer: 1¹¹/₂₀ litres

Step-by-step explanation:

The fractions need to be added.

Find a common multiple for them.

Common multiple = 20

Divide the multiple by the denominator of the fraction and multiply the numerator by the result you get:

= \frac{15 + 16}{20} \\\\= \frac{31}{20} \\\\= 1\frac{11}{20}

= 1¹¹/₂₀ litres
