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 scaling the original 5"×7" dimensions to 10"×14" by multiplying each side by a scale factor of 2. This involves using proportional reasoning to determine the size of grid squares for an enlarged drawing, which is a form of ratio and scale math.

Answer:

Ratio/scale multiplication (proportional math, using a scale factor to resize dimensions proportionally)
