Step-by-step explanation:
Solution: Evaluate: 2(1/4) + 2/5 : (-1/2) - 1/4
⇛(8+1)/4 + 2/5 : (-1/2) - 1/4
⇛9/4 + 2/5 : 1/2 + 1/4
Now,
Take the LCM of 4 and 5 is 20.
Again, take the LCM of 2 & 4 is 4.
so,
⇛(45+8)/20 : (2+1)/4
⇛53/20 : (-3/4)
Now, your have one doubt in your mind that is how? -3/5 came. so, friends the answer is very easy because ,we know that (-)*(-) is (+) . But in this case the sing will obtain (+) because -1/2 is < -1/4. After doing addition.
Therefore,
⇛53/20 : (-3/4)
⇛53/20 × (4/-3)
⇛(53×1)/{5×(-3)}
⇛53/-15 Ans.
