Question

What should be subtracted for 3/2 to obtain 2/5

Answer 1

Answer:

The answer is 19/10

Step-by-step explanation:

To find what should be subtracted from 3/2 to obtain 2/5

Step 1 = Let the number which should be subtracted from 3/2 be x

Now equate the subtraction of the numbers with their result

That is,

x - 3/2 = 2/5

x = 2/5 + 3/2

Take L.C.M of the denominators(5 and 2)

That is 10

So,

2/5 X 2/2 and 3/2 X 5/5[To make the denominators equal]

4/10 and 15/10

NOW,

x = 4/10 + 15/10

  = 19/10(The number which should be subtracted from 3/2 to obtain 2/5)
