2/3 * 21 cm
42/3 cm
= 14 cm
-----------
Two-thirds of 21 is calculated by multiplying 21 by the fraction ( \frac{2}{3} ). This can be done by first dividing 21 by 3, which gives you 7, and then multiplying that result by 2. Therefore, two-thirds of 21 is ( 2 \times 7 = 14 ). Thus, two-thirds of 21 is 14.
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

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.

2/3 + 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).
2/3 + 2/7 = 14/21 + 6/21 = 20/21
two thirds because 14/21 = 2/3
