Question 26
By interchanging which two signs the equation will be correct?
$$6 + 9 \times 2 - 3 \div 4 = 8$$
Solution
$$6 + 9 \times 2 - 3 \div 4 = 8$$
this results in a fraction so in order to get a whole number which is 8 it is important to place divide symbol such that a whole number is obtained
now if $$- and \div$$ is interchanged 9 gets divided by 3 thus resulting in a whole number
$$6 + 9 \times 2\div 3- 4 $$ (using BODMAS rule)
$$ 6 + \frac{ 9 \times 2}{ 3} - 4 $$
= 6+ 6 - 4 = 8
