Answer 2

Answer:

The answer 7/5 is false.

Step-by-step explanation:

Given:

• The rational number is 4/5, when you multiply it by 1/4 and 1 is added to the product, you get 7/5.

To find:

• That answer ( 7/5 ) is true or false ?

Solution:

We know that the rational number is 4/5, when you multiply it by 1/4, so we will do multiplicationof 4/5 and 1/4 and we will add 1 to its product, i.e, sum up 1 and it's product. The answer we get after multiplication is called product. Then afterwards we will check whether its true or false.

According to problem,

• = 4/5 × 1/4
• = 4/20

When 1 is added to the product, we get:

• = 4/20 + 1
• = (4 + 20)/20
• = 24/20
• = 12/10
• = 6/5

Check...

⟹ 6/5 ≠ 7/5

Hence the the answer given answer is false!!
