Not sure about one forth, but one fourth is (1/4)*n or n/4.
n + 25 =====
As a algebraic expression it is simply n/8
m = 60*n where m is the number of minutes.
The algebraic expression for three more than a number is: X + 3
N + 6
(6+n) n= a number
n = number. n + 5 ====
n + 25 =====
The algebraic expression for "4 less than the sum of a number and 5" is (n + 5) - 4, where n represents the unknown number.
6+n
n/6
n + 10
1/2 n
The algebraic expression is n + 100, where n is the unknown number.
As a algebraic expression it is simply n/8
Where the number=n: (n/2)+8.
m = 60*n where m is the number of minutes.
