ratio 1 hour 60 second

​

Answer 1

${\blue{\sf\underline{given}}}$

Find ratio of 1 hour to 60 seconds.

${\blue{\sf\underline{Solution}}}$

⠀⠀⠀We know 1 hour = 60 minutes.

⠀⠀⠀and, 1 minute = 60 seconds.

⠀⠀⠀so 60 minutes = 60×60

⠀⠀⠀= 3600seconds

⠀⠀⠀So, the ratio becomes

⠀⠀⠀$= \dfrac{3600}{60}$

⠀⠀⠀$= \dfrac{360}{6}$

____________

⠀⠀⠀${\boxed{\large{\bold{Some\:more\: examples}}}}$

1. 36 minutes to 80 seconds

${\blue{\sf\underline{we\:know}}}$

1 m = 80s

36m = 80 × 36

= 2800 seconds

${\blue{\sf\underline{So,\:the\:ratio\:becomes}}}$

⠀⠀⠀$= \dfrac{2800}{36}$

⠀⠀⠀$= \dfrac{700}{9} (simplest form)$

2. 80 seconds to 40 seconds

${\blue{\sf\underline{So,\:the\:ratio\:becomes}}}$

⠀⠀⠀$= \dfrac{80}{40}$

⠀⠀⠀$= \dfrac{8}{4} (simplest form)$

___________

${\boxed{\large{\bold{let's\: explore\:more}}}}$
