To find the expression that gives a product of 149, we can evaluate each option:
- 9 × 17 = 153
- 9 times 1 seventh = \(9 \times \frac{1}{7}\) = \(\frac{9}{7}\) (not equal to 149)
- 2 × 79 = 158
- 2 times 7 ninths = \(2 \times \frac{7}{9}\) = \(\frac{14}{9}\) (not equal to 149)
- 9 × 27 = 243
- 9 times 2 sevenths = \(9 \times \frac{2}{7}\) = \(\frac{18}{7}\) (not equal to 149)
- 2 × 19 = 38
- 2 times 1 ninth = \(2 \times \frac{1}{9}\) = \(\frac{2}{9}\) (not equal to 149)
None of the expressions result in a product of 149. It seems that there is no correct expression provided in the options that gives a product of 149.
