z/z = 1
so, multiply by that.
To find an expression equivalent to 15/19 with a denominator of 19z, you can use the concept of multiplying by 1. The key idea here is that multiplying any number by 1 does not change its value.
To change the denominator to 19z, we need to multiply both the numerator and denominator of 15/19 by a suitable expression that includes 19z.
To do this, we can multiply both the numerator and denominator by z. This is because multiplying by z will give us a denominator of 19z, as desired.
So, the equivalent expression is:
(15/19) * (z/z)
Multiplying the numerator and denominator gives us:
(15 * z) / (19 * z)
Therefore, the equivalent expression is:
(15z) / (19z)
