Answer 1

Explained below.

Explanation:

The question is:

Please answer me these questions or one: v please. My math class room is 700 m2, how much is 1/4 of the room? How long is 3/4 of the room? . How many minutes is 3/5 of a half hour? . It takes 4/7 of a liter of paint to paint a square meter of wall, if we want to paint 2/5 of a square meter of wall, how much paint will we need? . If it takes 2/5 of an orange to make a glass of orange juice, how many oranges do you need to make 2 and a half glasses?

(1)

Compute 1/4th of the math class room as follows:

`=700*(1)/(4)\\=175`

Thus, 1/4th of the math class room is 175 m².

(2)

Compute 3/4th of the math class room as follows:

`=700*(3)/(4)\\=525`

Thus, 3/4th of the math class room is 525 m².

(3)

Compute 3/5th of half an hour as follows:

`=30* \frac{3}[5}\\=18`

Thus, 3/5th of half an hour is 18 minutes.

(4)

A square meter of wall required 4/7 liter of paint.

Then 2/5 of a square meter will require,

`=(4)/(7)* (2)/(5)\\\\=(8)/(35)`

Thus, 8/35 liter of paint will be used to pain /5 of a square meter of the wall.

(5)

1 glass of orange juice can be made using 2/5 of an orange.

Then 2 and half glass will require,

`=(2)/(5)* 2(1)/(2)\\\\=(2)/(5)* (5)/(2)\\\\=1`

Thus, 1 orange will be required to make 2 and half glass of orange juice.
