-√4 + √(-48) + √121 + √(-108)

= -√(2²) + √(-1 • 3 • 4²) + √(11²) + √(-1 • 2² • 3³)

= -2 + 4√3 i + 11 + 6√3 i

= 9 + 10√3 i

Answer:

$\frac{7}{4}$

Step-by-step explanation:

Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.

Given ratio= elementary schools: middle schools:: 28:16

The ratio can be written as $\frac{28}{16}$

Now to write $\frac{28}{16}$ into simplest form, we need to divide both numerator and denominator by 4.

∴ elementary schools: middle schools= $\frac{\frac{28}{4} }{\frac{16}{4} }$

Hence, we get simplest ratio of elementary schools to middle schools= $\frac{7}{4}$
