in:ft = 12:1
To simplify the ratio of 14 ft to 21 ft, divide both numbers by their greatest common divisor, which is 7. This results in the simplified ratio of 2:3. Thus, the ratio of 14 ft to 21 ft simplifies to 2:3.
20:24
The ratio is 15:4
No, a 3 ft by 9 ft rectangle cannot be a scaled copy of a 3 ft by 1 ft rectangle. For two shapes to be scaled copies, their corresponding sides must maintain the same ratio. In this case, the ratio of the lengths (9:1) is different from the ratio of the widths (3:3), which means they are not proportional.
1:72
The ratio of the length of the side of a right angle triangle must be 3,4,5 16,56,65 are not in that ratio.
It is 1 to 2.
The ratio of 115 to 30 is ( 23/6 ).
1 yd = 3 ft → 9 yd : 9 ft = 9 x 3 ft : 9 x 1 ft = 3 : 1
It is 9 : 5.
If lengths are in the ratio a:b, then areas are in the ratio a2:b2 since area is length x length. If areas are in the ratio c:d, then lengths are in the ration sqrt(c):sqrt(d). Areas of decagons are 625sq ft and 100 sq ft, they are in the ratio of 625:100 = 25:4 (dividing through by 25 as ratios are usually given in the smallest terms). Thus their lengths are in the ratio of sqrt(25):sqrt(4) = 5:2 As perimeter is a length, the perimeters are in the ratio of 5:2.
There are 12 feet in 4 yards so the ratio is 4:12 feet.
