- a) 12.9
- b) 13.5
- c) 11.8
- d) 14.2
correct answer : a)
Explanation:
Convert the mixed fractions to decimals:
3 1/2 = 3.5
2 1/4 = 2.25
The expression becomes:
(3.5 * 2.4) + (2.25 ÷ 0.5) = 8.4 + 4.5 = 12.9.
मिश्रित भिन्नों को दशमलव में बदलें:
3 1/2 = 3.5
2 1/4 = 2.25
व्यंजक बन जाता है:
(3.5 * 2.4) + (2.25 ÷ 0.5) = 8.4 + 4.5 = 12.9.
