the previous one, burn? (Use

pls give step by step explanation​

Answer 1

Answer:

Answer is 54..........

Step-by-step explanation:

Solutions.........

First candle length = 25cm

Length of second candle = 25 + 5

= 30cm

It can be answered by ratio and proportion

We have to take one of the things in Fractions and the things are related to them in direct proportion ( on the other side of equal) in fractions

Let another time which is not given be x.....

$\frac{25}{30} = \frac{45}{x}$

$x = (\frac{45}{25} )30$

$x = 54$
