I showed the answer in long division! I suppose 6 divided by 489 is equal to
0.81
Try this option:
only the 1-st way, where 25x+40x=x(25+40)... =260.
Another way to calculate it is 25*4+40*4=100+160=260.
answer: way 1.
1 times 0.5
Is this what you mean?
Hopefully it is
<span> 16ft long shadow of a building when the building true height is</span> 40 ft
1 ft long shadow of a building when the building true height is <span>40/16 ft
</span>2 ft long shadow of a person when the building true height is <span>(40x2)/16 = 5ft (ans)
</span>
