Simplify
5 × [ 14 ÷ 13 × { 13 × 14 ÷ ( 14 × 14 )}]
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 5.
5 × [14 ÷ 13 × {13 × 14 ÷ (14 × 14)}]
= 5 × [14 ÷ 13 × {13 × 14 ÷ (196)}]
= 5 × [14 ÷ 13 × {(13 × 14)/196}]
= 5 × [14 ÷ 13 × {13/14}]
= 5 × [(14/13) × (13/14)]
= 5 × 1
= 5
