Three children shared a basket of mangoes in su... - JAMB Mathematics 1990 Question

You can use any whole numbers (eg. 1. 2. 3) to represent all the mangoes in the basket.

If the first child takes (\frac{1}{4}) it will remain 1 - (\frac{1}{4}) = (\frac{3}{4})

Next, the second child takes (\frac{3}{4}) of the remainder

which is (\frac{3}{4}) i.e. find (\frac{3}{4}) of (\frac{3}{4})

= (\frac{3}{4}) x (\frac{3}{4})

= (\frac{9}{16})

the fraction remaining now = (\frac{3}{4}) - (\frac{9}{16})

= (\frac{12 - 9}{16})

= (\frac{3}{16})
