Answer:

(a) Arts take longer

(b) By 2/9 hours

Step-by-step explanation:

Given

Arts = four over nine hours

Maths = two over nine hours

Solving (a): Which takes longer?

First, represent both as fraction

Arts = \frac{4}{9}\ hours

Maths = \frac{2}{9}\ hours

Convert fraction to decimal

Arts = \frac{4}{9}\ hours

Arts = 0.444\ hours

Maths = \frac{2}{9}\ hours

Maths = 0.222\ hours

By comparison:

0.444 > 0.222

Hence, Arts take longer

Solving (b): How much longer?

To do this, we calculate the difference.

Difference = Arts - Maths

Difference = \frac{4}{9} - \frac{2}{9}

Take L.C.M

Difference = \frac{4 - 2}{9}

Difference = \frac{2}{9}\ hours
