2/3 * 21 cm
42/3 cm
= 14 cm
-----------
To find two-thirds of 21, you multiply 21 by 2/3, which equals 14. Then, adding 166 to 14 gives you 180. Therefore, 166 plus two-thirds of 21 equals 180.
52/21 or 2 and 10/21
2/3 + 2/7 = 14/21 + 6/21 = 20/21
2/3 x 21 = 2 x 21 / 3 = 14
2/3 + 2/7 = 14/21 + 6/21 = 20/21
One third is 21/3 = 7 So two thirds of 21 = 7 x 2 = 14
14/21 = 2/3 or two thirds.
To find two-thirds of 21, you multiply 21 by 2/3, which equals 14. Then, adding 166 to 14 gives you 180. Therefore, 166 plus two-thirds of 21 equals 180.
52/21 or 2 and 10/21
2/21 is.
2
2/3 + 2/7 = 14/21 + 6/21 = 20/21
2/3 x 21 = 2 x 21 / 3 = 14
Multiply 21 with the numerator (2), then divide the result by the denominator (3).
two thirds because 14/21 = 2/3
2/3 + 2/7 = 14/21 + 6/21 = 20/21
2/3 × 21 cm = (2 × 21)/3 cm = 14 cm
