Question

a wall 7 1/5 m in height is being built after one day the masons had built 7/9 of the wall what height of the wall is yet to be built

Answer 1

Please Mark It As The BRAINLIEST

Height of wall

= 7 1 = 36

     5       5

Part built by the masons

= 7 of the wall

   9

= 7 X 36

   9       5

= 7 X 4

          5

= 28

    5

Part left

= 36 - 28

    5        5

= 8

   5

In Mixed Fraction

= 1 3

     5

Answer 2

Answer:

∴The height of the wall to be built =  $1\frac{3}{5}$m

Step-by-step explanation:

Given,

The total height of the wall =  7$\frac{1}{5}$m

The part of the wall built in one day = $\frac{7}{9}$

To find,

The height of the wall to be built

Solution:

The total height of the wall = 7$\frac{1}{5}$m = $\frac{36}{5}$m

Since  $\frac{7}{9}$ part of the wall is built in one day, the height of the wall completed in one day =  $\frac{36}{5}$× $\frac{7}{9}$

= $\frac{4X7}{5}$

= $\frac{28}{5}$m

The height of the wall completed in one day = $\frac{28}{5}$m

The height of the wall to be built = Total height of the wall - part of the wall built

= $\frac{36}{5}$ -  $\frac{28}{5}$

= $\frac{8}{5}$

= $1\frac{3}{5}$m

∴The height of the wall to be built =  $1\frac{3}{5}$m
