 
 <prompt> ```The tallest building for this world na 100 feet tall. If the second tallest na half of that height, and the third tallest na half of the second, and the fourth na one-fifth of the third, how tall all 4 buildings go be if dem put together?``` <response>: If di second tallest building na half of di first one wey dey 100 feet, e mean say e dey 100/2= 50 feet tall.
If di third tallest building na half of di second one wey dey 50 feet, e mean say e dey 50/2= 25 feet tall.
If di fourth building na one-fifth of di third one, e mean say e dey 25/5= 5 feet tall.
So, if you add all di four buildings together, e go be 100+50+25+5= 180 feet tall.

Di answer go be 180.
