4️⃣ 2 units equal to 5 marks​

Answer 1

Step-by-step explanation:

I think it is 1 unit is equal to 5 marks

Answer 2

Answer:

1 unit equal to 5 marks

Step-by-step explanation:

Five student got 25,10,30,15,20 marks in math test.

we need appropriate number that can measure all the marks when drawing a column.

For that we need to find common factor of all marks.

First we find highest common factor of 25,10,30,15,20.

$25=5*5\\10=5*2\\30=5*3*2\\15=5*3\\20=5*2*2$

Since common factor in all the marks is 5.

There for 5 is highest common factor of 25,10,30,15,20.

There for 1 unit equal to 5 marks is appropriate that can measure all the marks when drawing a column.
