Question

3/10 of a wall was completed on day 1, 4/14 of the wall was completed on day 2, 3/15 of the wall was completed on day 3 and the remaining on day 4, if the total length of wall is 513 1/3m , find.

1. What part of the wall was constructed on day 4?

2. How many meters of wall was constructed on day 4?

Answer 1

Answer:

1. 3/14ᵗʰ of the wall was constructed on day 4

2. 110 meters of wall were constructed on day 4

Step-by-step explanation:

Let the fraction of wall completed on 4th day be x

1. Since the wall constructed over 4 days was the whole of the wall,

the fraction of wall completed each day will add up to 1.

3/10 + 4/14 + 3/15 + x = 1

x = 1 - 3/10 - 4/14 - 3/15 = 3/14

2. Length of wall constructed on day 4 = 3/14 of 513 ⅓ m = (3/14) * (1540/3) = 110 m
