We will assume that "x" cents equals 5 quarters.
We kow that :
1 quarter = 25 cents
5 quarters = x cents.
To calulate, cross multiply, such that:
1*x = 25*5
==> x = 125 cents.
A variable is an unknown or an assumed value of any thing till it is known or it is solved..
A variable is any value varying.
A fixed value is a constant or a known value.
An expression is a mathematical operation or operations ( like addition, subtraction, multiplication, or division , powers, roots, factorials or any defined compositions) etc on numbers or variables.
Here between the number cents and 5 quarters we can establish a relation:
Let 5 quarters be equal to x cents.
So x = 5quarters..........(1) is the relation or equation.
x is the variable. 5quarters is the known value.
x can be any thing for which the relation is true or not true.
We know 1 quarter = 25 cents. So ,
x cents = 5*25cents , here 5*25 cents is an expression. So,
x cents = 5*25cents.
x cents = 125 cents.
x = 125. So x = 125 is the only value for which reation or equation at (1) is true or holds good. (For any other value of x the relation does not hold good. Or the relation is not true for values other than 125.)
5 x 25= 125
The value in cents of 5 quarters would be;
Since 1 quarter is 25 cents
and 1 nickel is equal to 5 cents
To find the value of cents in 5 quarters you would multiply
5 cents times 25 cents so it would equal 125 cents
the value in cents of 5 quarters
5 x 25= 125
so 125 cents
value of 1 quarter = 1/4
value of 5 quarters = 1/4 * 5 = 5/4
Now we'll convert it to percentage,
to do this we multiply it with 100% So,
5/4 * 100% = 125%
