To determine which expression gives a product of 149, we will evaluate each multiplication expression:
-
2 × 79:
\( 2 \times 79 = 158 \) (not equal to 149) -
2 × (7/9):
\( 2 \times \frac{7}{9} = \frac{14}{9} \) (not equal to 149) -
2 × (19):
\( 2 \times 19 = 38 \) (not equal to 149) -
2 × (1/9):
\( 2 \times \frac{1}{9} = \frac{2}{9} \) (not equal to 149) -
9 × 17:
\( 9 \times 17 = 153 \) (not equal to 149) -
9 × (1/7):
\( 9 \times \frac{1}{7} = \frac{9}{7} \) (not equal to 149) -
9 × (27):
\( 9 \times 27 = 243 \) (not equal to 149)
None of the expressions provided result in a product of 149. If "9 × 17" is considered, it gives 153, which is the closest, but still not equal to 149. So, there is no expression among those listed that results in a product of exactly 149.
