Step-by-step explanation:

☄ \underline{ \underline{ \text{Question }}}: The ratio of new houses to antique houses in a village is 4 : 5 . If there are 12 new houses , how many antique houses are there ?

☄\underline{ \underline{ \text{Solution}}} :

✏ Let , the number of antique houses in a village be ' x ' .

Then , According to the question :

\sf{ \frac{Number \: of \: new \: houses}{Number \: of \: antique \: houses}  \:  =  \:  \frac{4}{5}}

⤑\sf{ \frac{12}{x}  =  \frac{4}{5}}

Apply cross product property

⤑\sf{4 \times x = 12 \times 5}

⤑\sf{4x = 60}

⤑\sf{ \frac{4x}{4}  =  \frac{60}{4}}

⤑\sf{x = 15}

So, The number of antique houses in a village is 15.

\red{ \boxed{ \boxed{ \tt{Our \: final \: answer :  \boxed{ \bold{15}}}}}}

If I turned 9 on November 9th, 2015, exactly how old am I now? (Oct 16th, 2021)
inysia [295]

The answer to this is quite simple my friend.

So if you were 9, purely turning on November 9th of 2015 at a undisclosed time, you would've been born in November of 2006. Currently, now of October 16, 2021, you would be:

Add:

4 + 10 + 1 = 15

So you would be 15 years old.

Hope this helps, currently it's 10/17/2021 for me and 1:56 am (EST).

Have a nice morning, night, dusk etc.
