A machine produces 247 bolts in 26 minutes. At the same rate, how many minutes would it take to produce 209 bolts? \( \square \) minutes

\( ( 7 \times 5 ) \quad \bmod 6 \)

QUESTION TWO Express each of the following as a single, simplified fraction. 2.1. \( \frac{4}{9}-\frac{2}{3}+\frac{7}{12} \) 2.2. \( \frac{-8}{13} \times \frac{5}{24} \div-\frac{25}{13} \) 2.3. \( \left(\frac{3}{7}+\frac{1}{4}\right) \times\left(2-\frac{69}{38}\right) \)

(f) \( \frac{1}{6} \times \frac{3}{8}-\frac{1}{10} \)

\( 37 ; 33 ; 29 ; x ; 21 ; \ldots \). Write down the value of \( x \). Determine the \( n^{\text {th }} \) term of the number pattern. Determine the \( 15^{\text {th }} \) term of the sequence. Which term is the first to have a negative value.

Find \( -\frac{8}{15}-3 \frac{4}{5} \). Write your answer as a mixed number in simplest form.
