Answer 1

Step-by-step explanation:

1½ + 2½

1.5 + 2.5

= 4 metres

Answer 2

Answer:

Therefore the converted value of One and a half metres and two and a half metres into a decimal fraction is 1.5 m and 2.5 m respectively and their addition is 4 m.

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

One and a half metre and two and a half metres​.

We have to convert One and a half metres and two and a half metres into a decimal fraction.

We will be using the given data,

$One\;and \;a\;half\;metre=1+\frac{1}{2}$

We will divide 1 by 2 we get 0.5,

$=1+0.5\\=1.5\;m$

Now,

$Two\;and\;a\;half\;metres=2+\frac{1}{2}$

We will divide 1 by 2 we get 0.5,

$=2+0.5\\=2.5\;m$

Now we will add 1.5 m and 2.5 m.

$=1.5+2.5$

Above values, we will write 1.5 is 1 plus 0.5 and 2.5 is 2 plus 0.5 as below,

$=1+0.5+2+0.5\\=1+2+0.5+0.5\\=3+0.5+0.5\\=3+1\\=4\;m$

Therefore the converted value of One and a half metres and two and a half metres into a decimal fraction is 1.5 m and 2.5 m respectively and their addition is 4 m.
