Answer 1

Given data:

Mansi and Meghna cleaned 2/5 and 3/5 of their school premises respectively.

To find:

How many parts did the two clean together?

Step-by-step explanation:

• Mansi did 2/5 cleaning and Meghna did 3/5 cleaning of the premises.

• In order to find the total cleaning by them, we must find their sum.

• Now, 2/5 + 3/5 = (2 + 3)/5 = 5/5

• Thus they cleaned the whole school premises, since 5/5 = 1.

Answer: Option 2️⃣ 5/5 is correct.

$= > \dfrac{2}{5} + \dfrac{3}{5}$

$= > \dfrac{2 + 3}{5}$

$= > \dfrac{5}{5}$

Hence, they both have cleaned together 5/5 part of the school which equals to the whole part 1.

• 1 is the whole number of 5/5 fraction.

• 5/5 or 1, both the answers are equal.

• since the question is asking about how many parts did they both cleaned together so the required answer is option B => 5/5
