option 1. 18
2. 25
3. 36
4. 15

Answer 1

Answer:

The correct answers to the given problem will be option (2) 25 and option (4) 15.

Step-by-step explanation:

The original length of the log of wood is given to us as: 40 inch,

The ratio in which the log of wood was cut down to is $5:3$

We can represent this by assuming a variable $x$ and the resulting expression will be as follows:

$5x+3x=40$

$8x=40$

Simplifying it, we get:

$x=5$

Now, we can calculate the length of the pieces of log by multiplying it by 5 and 3 as:

$5x=5(5)$

$5x=25$ inch

similarly, the second piece will be:

$3x=3(5)$

$3x=15$ inch

So, the two pieces of the log of wood in ratio 5:3 would be 25 inch and 15 inch long respectively.
