Question

how many times should 5/8 be added to 5/8, so that the sum is 5?

Answer 1

5/8 should be added 8 times to get 5 as 5/8 *8 =5

Answer 2

We have to add 7 times to get 5.

Step-by-step explanation:

When we add $\frac{5}{8}$ to $\frac{5}{8}$ for one time it will give $(\frac{5}{8} + \frac{5}{8}) = 2 \times (\frac{5}{8})$.

Again, when we add $\frac{5}{8}$ for the second time, then it will give $(\frac{5}{8} + \frac{5}{8} + \frac{5}{8}) = 3 \times (\frac{5}{8})$.

In this way when we add $\frac{5}{8}$ with $\frac{5}{8}$ for n times then the final sum will become $(n + 1) \times (\frac{5}{8})$.

Now, for making the sum equal to 5, (n + 1) should be equal to 8.

So, n + 1 = 8

⇒ n = 7

Therefore, we have to add for 7 times to get 5. (Answer)
