Question

16 ¾ meters , i used 4 ½ meters in curtain and 6 ⅕ for bedsheet how many meters left not used

Answer 1

• 121/20 meters

Explanation:

To find the number of meters left unused, we need to subtract the meters used from the total meters available.

Start by converting the mixed numbers into improper fractions:-

-------------------------------------------------

• 16 ¾ meters can be written as (16 * 4 + 3)/4 = 67/4 meters.

• 4 ½ meters can be written as (4 * 2 + 1)/2 = 9/2 meters.

• 6 ⅕ meters can be written as (6 * 5 + 1)/5 = 31/5 meters.

-------------------------------------------------

Now, let's subtract the meters used from the total meters available:

→ 67/4 - 9/2 - 31/5.

In order subtract fractions, we need a common denominator. The least common multiple of 4, 2, and 5 is → 20.

• 
  `\sf 67/4 = (67 * 5)/ (4 * 5) = 335/20\; meters.`

• 
  `\sf 9/2 = (9 * 10)/ (2 * 10) = 90/20\; meters.`

• 
  `\sf 31/5 = (31 * 4)/ (5 * 4) = 124/20 \;meters.`

Now, let's subtract:

`\sf 335/20 - 90/20 - 124/20 =`

`\sf (335 - 90 - 124)/20 =`

`\sf 121/20 meters.`

Therefore, there are 121/20 meters left unused.
