2/5
False: Ratio areas= 16 : 64 = 1 : 4 Ratio of sides = sqrt(ratio of areas) = 1 : 2
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).
1::2 is the simplest form...
18 to 32
The ratio is 8 : 16 or 8/16 or 1/2 or 0.5 .
2
Expressed as a ratio in its simplest form, 16:24 is equal to 2:3.
16 ÷ 1 = 32 ÷ 2 16 = 16
16/24 = 2/3
It is: 16/24 = 2/3
It is 2 : 1 : 8.
1/8 as a ratio is equivalent to 2/16
It is: 8 to 1
It is: 2/1
Ah, what a happy little question! To find the equivalent ratio to 16:6, we can simplify it by dividing both numbers by their greatest common factor, which is 2. So, 16 divided by 2 is 8, and 6 divided by 2 is 3. Therefore, the equivalent ratio is 8:3. Remember, there are no mistakes in ratios, just happy little simplifications!
The ratio is 3:2
