To simplify the expression StartFraction 10 y z over negative 2 z EndFraction, you can cancel out the common factor of z in the numerator and denominator:
StartFraction (10 y z) / (negative 2 z) EndFraction = StartFraction 10 y / negative 2 EndFraction
Simplifying further, we obtain:
StartFraction 10 y / negative 2 EndFraction = negative 5y
Therefore, the simplified form of the expression is negative 5y.
To simplify the given expression, we need to divide the numerator by the denominator.
The expression is “10yz / (-2z)”.
First, we can cancel out the common factor of z in the numerator and denominator:
10yz / (-2z) = 10y / (-2)
Next, we divide 10y by -2:
10y / (-2) = -5y
Therefore, the simplified form of the given expression is -5y.
