If 21 is a factor of a number, then the factors of 21 must also be factors. So 3 and 7
There are only two common factors for 56 and 21. They are 1 and 7.
The factors of 63 are 1, 3, 7, 9, 21, and 63. Pick two.
Composite is the opposite of prime which is a number with only two factors. 1 and itself.Composite has more than two factors so I guess a composite number is your answer.
two fractions are equivalent 21 over 23 = 42/46, 63/69
Two equivalent fractions for 21/35 are: 42/70, 3/5.
21 over 30 and 7 over 10
14 over 22 21 over 33
1 over 7 is the equivalent to 3 over 21.
1/7 is one of then
One fraction that is equivalent is 10 over 14. Another is 15 over 21.Yours truly.
