number.​

Answer 1

Required Answer:-

GiveN conditions:

• If the denominator of 3/4 is increased by a number.

• If the numerator of the fraction is doubled, the result is 1.

We have to find:

• The required fraction?

Step-by-step Explanation:

The fraction given is 3/4. According to conditions, let the unknown number added to the denominator be x.

Then,

• New numerator = 3 × 2 = 6
• New denominator = 4 + x

And now, the fraction is 1. Comparing these two situations,

⇒ New num. / New den. = 1

⇒ 6 / 4 + x = 1

⇒ 4 + x = 6

⇒ x = 2$.$

Therefore:

• The required number added to the denominator is 2

Answer 2

Answer:

3/4 + x= 3/4 ×2

3+4x/4 = 3/2

6+ 8x = 12

8x = 12-6

x= 6/8

x= 3/4
