Solve the following problem using cross-multiplication. Ja’Quin draws a picture of a horse that measures 7 inches by 4 inches. He increases the size of the picture on a photocopier so that its new width is 6 inches. What is the new length of the picture? Round to the nearest tenth.
Responses:
1.5 inches
1.2 inches
10.5 inches
42.0 inches
To solve this problem using cross-multiplication, we set up the following equation:
7 inches / 4 inches = 6 inches / x inches
Cross-multiplying gives us:
7 * x = 4 * 6
7x = 24
x = 24 / 7 ≈ 3.43
Therefore, the new length of the picture is approximately 3.4 inches. Rounding to the nearest tenth, the answer is 3.4 inches.
