16/18 = 8/9
The ratio is 16 to 81.
area of triangle 1 would be 16 and the other triangle is 9 as the ratio of areas of triangles is the square of their similar sides
6:8, 9:12, 12:16 etc.... You should multiply or divide both numbers by the same number. ex: 3x2=6 and 4x2=8 3x3=9 and 4x3=12 3x4=12 and 4x4=16 But if we have this ratio for example (12:16), we could also use division. ex: 12÷2=6 and 16÷2=8
If the diameter of a circle is quadrupled, the circle's area goes up 16 times as area is proportional to diameter squared. Remember area = pi /4 times diameter squared -------------------------------------------------------------------------- In any ratio of shapes: whatever the ratio of the lengths, the ratio of the areas is the square of that ratio. In this case, the ratio is 1:4, so the areas are in the ratio of 1²:4² = 1:16; ie as the length of the diameter is quadrupled (ratio 1:4), the area becomes 16 times bigger (1:16).
They are: 8 to 18 and 16 to 36
The ratio is 16:9.
14:16
1 ton = 2,000 pounds 16 tons = 32,000 pounds The ratio is 9/32,000 .
It is: 9 to 4
It is 36/16 = 9/4.
That is a 16:9 aspect ratio.
It is: 1 to 4
5 : 9 = 10 : 18
Expressed as a ratio in its simplest form, 16:24 is equal to 2:3.
It can be simplified as: 3 to 16
9/16 = 3/4
