It looks like you're dealing with a set of mathematical expressions or equations that need to be solved. Let's break them down step by step.
First Expression:
\((7 - 6.35) : 6.5 + 9.9\)
Calculate \(7 - 6.35\): \[ 7 - 6.35 = 0.65 \]
Now divide by \(6.5\): \[ 0.65 : 6.5 = \frac{0.65}{6.5} = 0.1 \]
Finally, add \(9.9\): \[ 0.1 + 9.9 = 10 \]
Second Expression:
\((1.2 : 36 + 1.2 : 0.25 - 1) : (16 : 24)\)
Calculate \(1.2 : 36\): \[ 1.2 : 36 = \frac{1.2}{36} = 0.0333 \text{ (approx.)} \]
Calculate \(1.2 : 0.25\): \[ 1.2 : 0.25 = \frac{1.2}{0.25} = 4.8 \]
Now, add the two results: \[ 0.0333 + 4.8 = 4.8333 \text{ (approx.)} \]
Subtract \(1\): \[ 4.8333 - 1 = 3.8333 \text{ (approx.)} \]
Now calculate \(16 : 24\): \[ 16 : 24 = \frac{16}{24} = \frac{2}{3} \approx 0.6667 \]
Now divide the two results: \[ 3.8333 : 0.6667 \approx 5.75 \text{ (approx.)} \]
Final Answers
- First expression: \(10\)
- Second expression: \(5.75\) (approx.)
