Question

Can Someone Please Help Me With This, Thanks! :)

Answer 1

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

Answer 2

Answer:

405 bricks in total

Step-by-step explanation:

1 - 5/9 = 4/9

So 4/9 of the bricks are remaining, and "the last 180 bricks" is equal to 4/9

Using ratio method:

4/9 : 180

5/9 : x

x = 180 × 5/9 ÷ 4/9

x = 225

So 180 + 225 = 405 bricks in total
