Question

Express 12 seconds as a percentage of 3 minutes 20 seconds. Please give explanation

Answer 1

Answer:

# Given:

First value of time given = 12 seconds

Second value of time given = 3 mins 20 sec

# To find:

Express the 12 seconds as a percentage of 3 mins 20 second .

# Concept:

We can find the percentage in two types :

1 st type :

$\frac{F}{S}×100$

Where,

F = First value of time given

S = Second value of time given

2 nd type :

(F×100)÷S

And convert the minute into second to find the percentage .

So , 3 min 20 sec

( 1 min = 60 sec )

= (3×60)+20 sec

= 180 sec + 20 sec

= 200 sec

# Solution:

First , we should find the solution with 1 st type of solution given :

$\frac{12\:sec}{200\:sec}×100$

$\frac{12}{2}$

= 6 % .

Now , we should find the solution with 2 nd type of solution given :

$(12×100)÷200$

$1200÷200$

= 6 % .

So , we have find the solution in two types and by both type the answer comes 6 % .

# Answer:

So , the 12 sec as a percentage of 3 min 20 sec is 6 % .

# Extra information:

To find the percentage to decimal:

$\frac{P}{100}$

Where,

P = Percentage

To find area of the triangle:

$At=\frac{H×B}{2}$

Where,

At = Area of the triangle

H = Height

B = Breadth

To find area of the rectangle:

$Ar=L×B$

Where,

Ar = Area of the rectangle

L = Length

B = Breadth

Answer 2

Step-by-step explanation:

GIVEN:

FIRST VALUE OF TIME = 12 SECOND

SECOND VALUE OF TIME=3 MIN 20 SECONDS.

TO FIND:

12 SECS AS PERCENTAGE OF 3 MIN 20 SECONDS.

METHODS:

1.F/S ×100

F= FIRST VALUE OF TIME.

S= SECOND VALUE OF TIME

2. F×100/S

SOLUTION:

FIRST FIND USING FIRST METHOD:

F/S

F=12 SECONDS

S=3 MIN 20 SECOND =(3×60)+20 SECONDS =200 SECONDS.

NOW,

12/200×100=6 %

NOW USING SECOND METHOD:

F×100/S

F=12 SECONDS

S=200 SECONDS

NOW,

12×100/200=1200/200=6%

HENCE 12 SECONDS IS 6 % OF 3 MIN 20 SECONDS.

VERIFICATION:

6/100×200=12 SECONDS
