To determine which expression yields a product of 149, we can evaluate each option.
- 9 × 17 = 153
- 9 times 1 seventh = 9 × (1/7) = 9/7 (not an integer)
- 2 × 19 = 38
- 2 times 1 ninth = 2 × (1/9) = 2/9 (not an integer)
- 9 × 27 = 243
- 9 times 2 sevenths = 9 × (2/7) = 18/7 (not an integer)
- 2 × 79 = 158
None of the provided expressions result in a product of 149. It appears there may have been an error in the options, or none of the options satisfy the requirement for yielding 149.
