Let's solve the problems shown in the image:

**6. \( 23 + 25 - 48 = \)**

First, add 23 and 25:
\[ 23 + 25 = 48 \]

Then, subtract 48:
\[ 48 - 48 = 0 \]

So, the answer is:
\[
0
\]

**7. \( (2)(3)(4) = \)**

Multiply the numbers together:
\[ 2 \times 3 = 6 \]
\[ 6 \times 4 = 24 \]

So, the answer is:
\[
24
\]

**8. \( (-8)(-7) = \)**

Multiplying two negative numbers gives a positive result:
\[ (-8) \times (-7) = 56 \]

So, the answer is:
\[
56
\]

**9. \( (-1)(2)(-4) = \)**

First, multiply \(-1\) and \(2\):
\[ (-1) \times 2 = -2 \]

Then, multiply \(-2\) and \(-4\):
\[ (-2) \times (-4) = 8 \]

So, the answer is:
\[
8
\]

**10. \( \left(\frac{4}{5}\right)\left(\frac{2}{3}\right) = \)**

Multiply the numerators and denominators:
\[ \frac{4 \times 2}{5 \times 3} = \frac{8}{15} \]

So, the answer is:
\[
\frac{8}{15}
\]
