28/63 = 4/9 28/7=4 63/7=9
The same as the GCF of 28 and 7 (7 is the remainder when you divde 63 by 28).
Expressed as a proper fraction in its simplest form, by dividing the numerator and denominator by 7, 28/63 is equal to 4/9 or four ninths.
prime factorizing, 63 = 3*3*7 and 28 = 2*2*7, so the answer is 7.
7/9 - 4/7 = 49/63 - 36/63 = 13/63
28/63 = 4/9 28/7=4 63/7=9
cause 4/7 = 36/63 and 28/63
63/28 - 4/28 = 59/28
3 + 4 = 27 + 28 = 55 7... 9 ... 63 .. 63 .. 63
4/7 & 4/9 Bring to the same denominator of 63 ( 7 x 9) Hence we multiply the numerators by 9 & 7. (4 x 9) / 63 & (4 x 7) / 63 36/63 & 28/63 Since they are the same denominator , we now. compare the numerators 36 > 28 It follows 36/63 > 28/63 => 4/7 > 4/9
The same as the GCF of 28 and 7 (7 is the remainder when you divde 63 by 28).
7 is a factor of 28 because 4 x 7 equals 28. 7 is a factor of 63 because 9 x 7 = 63. That makes 7 a common factor of 28 and 63. The factors of 28 that are larger than 7 are 14 and 28. The factors of 63 that are larger than 7 are 9, 21 and 63. Since none of those numbers are the same, that makes 7 the greatest common factor of 28 and 63.
Because 7 is a factor of 28 and 63 and 7 is a prime number.
The factors of 28 are: 1, 2, 4, 7, 14, 28 The factors of 63 are: 1, 3, 7, 9, 21, 63
Factors of 28: 1, 2, 4, 7, 14, 28Factors of 63: 1, 3, 7, 9, 21, 63Factors of 49: 1, 7, 49GCF (28, 63, 49) = 7
63
Expressed as a proper fraction in its simplest form, by dividing the numerator and denominator by 7, 28/63 is equal to 4/9 or four ninths.
