Question

Can u solve plzz ques 13..​

Answer 1

Answer:

The answer is 119/60

Step-by-step explanation:

To find the number

Step 1 = Take the L.C.M of the denominators(4, 3 and 5)

That is 60

Now make the denominators equal

3/4 X 15/15, 1/3 X 20/20 and 2/5 X 12/12

45/60, 20/60 and 24/60

Now add these three numbers as per the question

That is,

= 45 + 20 + 24/60

= 89/60(3/4 + 1/3 + 2/5)

Step 2 = Let the unknown number which is to be subtracted from 89/60 be x

Now equate the subtraction with their derivative(1/2)

x - 89/60 = 1/2

x = 1/2 + 89/60

  = 60 + 178/120

  = 238/120

x = 119/60(The number which is to be subtracted from 89/60
