Answer:
405
Step-by-step explanation:
So he built 5/9 of the wall, than added the extra 180 bricks to finish the wall.
so 5/9 + 180 = 9/9
so 180 = 4/9 Because 5/9 + 4/9 = 9/9
So to figure out how many bricks are in the wall we want to know what 1/9 of bricks equals and to work this out we need to divide 180 by 4
which equals 45.
Now we know that 1/9 = 45
so now to figure out what 9/9 is just multiply 45 by 9 which equals 405
One approach that might be a great help would be if you would look
at the choices ... those things at the bottom of the question that you
didn't give us.
-- One leg is 3 times the length of the other leg.
-- Any right triangle that has one leg three times as long as the other
leg is similar to this triangle.
I'll bet that if you look through the choices, you'll find one there.
