40 * 16 ------ +240 040 ----------- 640 the answer is 640
640/240 = 2.666 or 2 and 2/3 inches. 480/240 = 2 inches So the image is 2.6666x2 inches, or about 5.33 (5 and 1/3) inches squared.
640 ÷ 8 = 80
40 x 10 = 400 40 x 6 = 240 40 x 16 = 640
Exactly 48 fives go into 240 (240/5 = 48)
40 * 16 ------ +240 040 ----------- 640 the answer is 640
You can do this problem by multiplying by the reciprocal aka 16/1so 640 *16 =640 * 16 = 10 240
