Question

Gabriella bought a pile of bricks to build a brick wall. Yesterday, she used \dfrac{5}{8} 8 5 ​ start fraction, 5, divided by, 8, end fraction of the bricks. Tomorrow, she plans to use another \dfrac{1}{4} 4 1 ​ start fraction, 1, divided by, 4, end fraction of the original brick pile. What fraction of the brick pile will she have left after tomorrow? of the brick pile

Answer 1

Total bricks remaining after tomorrow=1/8x

Explanation:

Let

Total number of bricks=x

Bricks used Yesterday=5/8x

Bricks planned for Tomorrow =1/4x

Total used brick=yesterday + Tomorrow

=5/8x+1/4x

= 5+2/8x

=7/8x

Total bricks remaining= Total number of bricks + Total number of used bricks

= x - 7/8x

= 8x-7x /8

= x/8

Equivalent to

1/8x

Total bricks remaining after tomorrow=1/8x
