To reduce the number 21, you can find its prime factors, which are 3 and 7, since 21 = 3 × 7. Alternatively, you could simplify it as a fraction by expressing it over a common denominator, such as 21/1, which can be reduced by dividing both the numerator and denominator by their greatest common factor (which is 1 in this case). If you're looking to reduce the value, you could subtract a number, like reducing it to 20 by subtracting 1.
It is 21/32
The same way you reduce a normal fraction: 14/21 = 2/3, so 5 14/21 = 5 2/3.
77 over 21 = 11/377 ÷ 7 = 1121 ÷ 7 = 3
21/34. 21 and 34 have no common factors (21=3x7, 34=2x17) so it's impossible to reduce it any further.
Yes; 3/7
14/21 = 2/3
No
It is 21/32
It is: 21/63 = 1/3
3/21 = 1/3
To 21/50
11/21
The same way you reduce a normal fraction: 14/21 = 2/3, so 5 14/21 = 5 2/3.
The fraction 21/100 cannot be reduced any more.
yes because 3 goes into 9 and 21. so 9/21 simplified is 3/7.
21/27 = 7/9 by dividing the numerator and denominator by 3
6/7
