First of all, recall that 1.5m is the same as 150cm.

Now, we simply build a proportion where we consider 48 to be 100, and wonder what 150 will be:

$48\div 100 = 150 \div x$

Solving for x, we have

$x = \dfrac{150\cdot 100}{48}=\dfrac{15000}{48} = 312.5$

Which actually makes sense, because we're stating that 1.5m is about 300% of 48cm, which means three times as much. Which is true, because three times 48cm means 144cm, which is about 1.5m
