Question

37. Rohit spent the
reciprocal of 5/7 hours on his
Maths project. How long did
he spent on his Maths project?​

Answer 1

Answer:

He spent 1.4 hours on the Maths Project

Step-by-step explanation:

We must know that,

The Reciprocal of a number is just 1 ÷ (the number) and the product of a number and its Reciprocal = 1

For eg:- Let the number be x

Its Reciprocal = 1 ÷ x = (1/x)

Now,

x × (1/x) = 1

Now, back to our Question,

Rohit spent the reciprocal of 5/7 hours on his Maths project.

So, reciprocal of 5/7 = 1/(5/7) = 1 × 7/5 = (7/5)

Now, 7/5 = 1.4

Thus, He spent 1.4 hours on the Maths Project
