Fraction sums, and a note on drawing hills
Arithmetic with fractions, the word 'painting', and advice on rendering terrain
The upper part of the sheet continues the fraction arithmetic of the facing page, with figures such as 8 2 4 11 and columns of thirds and sixths worked by cross-multiplication. Elsewhere the single word Pittura (painting) is written upside down. A note on landscape advises reading the shapes of the land and its divisions along the summits and flanks of the hills, and rendering whatever faces the viewer in its true form.

Continued fraction calculations
Rows of numbers and fractions (8 2 4 11; thirds, sixths and twelfths) are worked through with crossed strokes. The figures carry on the reckoning begun on the preceding page.
Reading the shapes of the hills
The note directs the eye to the summits and the flanks of the hills, where the shapes of the terrains and their divisions can be read. It treats the land itself as a set of legible forms to be observed before drawing.
Render what faces you in its true form
The advice closes that in the things turned toward the viewer, one should render them in their proper form. Placed beside the inverted word Pittura, it reads as a precept for representing landscape in painting.
