Answer 2

➤ Answer :-

Find the simplest form of the ratio 45 seconds to 1 hour :-

1 hour = 60 minutes

60 minutes = 3600 seconds

So,

$\tt \longrightarrow45:3600 = \dfrac{45}{3600}$

$\tt \longrightarrow \cancel \dfrac{45}{3600} = \dfrac{1}{80} = \boxed{ \tt 1: 80}$

$\Huge\therefore$The simplest form of the ratio is 1:80.

If 9:15 :: x:25, then find the value of x.

$\tt \longrightarrow9:15:: \sf{x}: \tt25$

Here, to find the value of x in the given sum, we use the formula :- a $\times$ d $=$ b $\times$ c

Here,

a = 9 ; b = 15 ; c = 'x' ; d = 25

So,

$\tt \longrightarrow 9 \times 25 = 15 \times \sf( x)$

$\tt \longrightarrow \sf(x) = \tt \dfrac{9 \times 25}{15}$

$\tt \longrightarrow \cancel \dfrac{225}{15} = \boxed{ \tt15}$

$\Huge\therefore$The value of 'x' is 15.

The area of a rectangular park is 300m². If the length of the park is 25 metres, find the breadth

Given that,

Area of the rectangular park :- 300 m²

Length of the rectangular park :- 25 metres

So,

Breadth of the park :-

$\large \dashrightarrow\mathfrak \orange{ \boxed{ \mathfrak \gray {\frac{Area \: of \: Rctangle}{Length \: of \: Rectangle}} }}$

$\tt \longrightarrow \dfrac{300}{25}$

$\tt \longrightarrow \cancel \dfrac{300}{25} = 12$

$\Huge\therefore$The breadth of the rectangular park is 12 metres.
