Evaluate: -4+sqrt(16)-(7)/(15)+sqrt((49)/(225))

Expression: $-4+\sqrt{ 16 }-\frac{ 7 }{ 15 }+\sqrt{ \frac{ 49 }{ 225 } }$

Evaluate the square root

$-4+4-\frac{ 7 }{ 15 }+\sqrt{ \frac{ 49 }{ 225 } }$

Evaluate the square root

$-4+4-\frac{ 7 }{ 15 }+\frac{ 7 }{ 15 }$

Since two opposites add up to $0$, remove them from the expression

$-\frac{ 7 }{ 15 }+\frac{ 7 }{ 15 }$

The sum of two opposites equals $0$

$0$
