Question

Express 1560 m as a percentage of 25 km

Answer 1

Answer:

$1560$ m is $6.24$% of $25$ km.

Step-by-step explanation:

Given : A distance of 25 km.

To find : Express 1560 m as a percentage of 25 km.

Solution :

• Here, a distance of $25$ km is given.
• We have to find that how much is the $1560$ m as a percentage of $25$ km.
• Let, $x$ be the percentage of $25$ km that equals to $1560$ m.
• As we know that,

      $1$ km = $1000$ m

• Now, convert $1560$ m into kilometres, we get

     $1560 m = \frac{1560}{1000}$

              $= 1.56$ km

• According to given conditions, we get

     $x$% of $25$ km = $1.56$ km

        ∴ $\frac{x}{100} *25=1.56$

             ∴ $25x = 1.56*100$

             ∴ $25x = 156$

               ∴ $x = \frac{156}{25}$

               ∴ $x = 6.24$ %

• ∴ $1560$ m is $6.24$% of $25$ km.

Answer 2

Here we have to express 1560 m as a percentage of 25 km.

For, this first we will have to equalize the units.

we know that,

    1 km = 1000 m

Therefore, 1560 m = 1560 / 1000

                               = 1.56 km

Let, x be the percentage of 25 km that equals 1.5 m

So, x % × 25 = 1.5

      x/100 × 25 = 1.56

                     x = 156 / 25

                      x = 6.24 %

Hence, the answer will be 6.24 %
