Question

voila, youve got a grid! now repeat the same procedure on your paper or canvas: youve now got a grid on your work surface that perfectly matches the grid of your reference photo. bravo! because this painting will be the exact size as the reference photo, the squares on this canvas are also 1 square inch. if this painting was going to be 10\ x 14\, then the squares would need to be 2 square inches, because \\(\frac{5}{7} \times \frac{2}{2} = \frac{10}{14}\\) 10. according to the text, what kind of math do you need to do in order to enlarge the drawing? the kind of math you will need is...

Explanation:

The text shows a proportion $\frac{5}{7} \times \frac{2}{2} = \frac{10}{14}$ to scale up the grid size for an enlarged drawing, which uses ratio and proportion (a type of algebraic/ratio math focused on equivalent fractions for scaling).

Answer:

Ratio and proportion (fraction-based scaling math, using equivalent fractions to calculate the scale factor for enlarging the grid and drawing)
