Question

3 1/4 hours convert in minutes

Answer 1

Hello mate.

Thanks for asking this question..

Your answer is =>

we have given the value of time as =>

$=> \:3 \frac {1}{4} \:hrs$

this value is in hours.so ,first we convert it into complete fractional value as =>


we multiply the denominator with external complete value i.e. 3 and add the nominator in it.


$=>\:3\frac{1}{4} \:= \: \frac {(3 \times 4)+1}{4}= \: \frac {13}{4}$

hence , our complete fractional value is =>

$=>\:\frac {13}{4} hrs$

hence , to convert the time in hours into minutes , we multiply the given value by 60.

$=> \:{\frac{13}{ \cancel {4}} }\times { \cancel {60}}$

$=> 13 \times 15 \:= \:195 \:minutes$

so ,

our value of time in minutes is 195 minutes.



$\boxed {BeBRAINLY}$
$\boxed {BeHAPPY}$

Answer 2

Given:-

time = 3 $\frac{1}{4}$ hrs.

Since, it is given in mixed fraction,

so, firstly, we have to convert this into a simple fraction,

Multiply 3 by the denominator, that is 4 , which will be equal to 12 ,

then add the numerator, that is 1 , so after adding 1 , result will be 13, but denominator will not change, so it will be written as ,

= $\frac{13}{4}$

now,

we know that ,

1 hour = 60 min.

hence,

$\frac{13}{4}$ hours

= $\frac{13}{4}$ × 60

= $\frac{13}{\cancel{4}}$ × $\cancel{60}$

= 13 × 15

= 195 minutes .....answer!
