Answer 1

Answer:

(3/10) + (2/5) - (5/20) = 0.45

Step-by-step explanation:

⟹ (3/10) + (2/5) - (5/20)

Remove all the brackets

⟹ 3/10 + 2/5 - 5/20

Making denominator same

⟹ 3×2/10×2 + 2×4/5×4 - 5/20

Solving it further, we get

⟹ 6/20 + 8/20 - 5/20

Now, The denominators are same. Adding numerators and taking denominator as common

⟹ 6+8-5/20

Performing calculation

⟹ 9/20

Transform fraction into decimal

⟹ 0.45

Hence, (3/10) + (2/5) - (5/20) = 0.45
