No
21/3 = 7
21/2 = 10.5 so not a whole number
2 goes into 20 or 22 but not 21
'3' 6 / 3 = 2 21/3 = 7
1, 3, 7, 21.
6/63=3(2)/3(21)=2/21 2/21 times.
21 with remainder 2.
2/3 x 21 = 2 x 21 / 3 = 14
2/3 of 21 = 14
(1+2)*(3+4)=21 3*7 = 21
Yes, 1*21 and 3*7 equal 21, and 1*34 and 2*17 equal 34.
2/3 x 21 = 14
It is (3 + 21)/2 = 24/2 = 12
1, 2, 3, 6, 7, 14, 21, 42. (1 x 42, 2 x 21, 3 x 14, 6 x 7)
1/3 + 2/21 = 7/21 + 2/21 = 9/21 = 3/7
