1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4 = -0.25 + 0.5 - 0.25 + 0.6 + 0.4 = 0.6
thats wrong
Apologies for the mistake. Let's calculate it correctly:
1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 20.
(5/20) - (10/20) + (10/20) - (5/20) + (12/20) + (8/20)
Combining the fractions with the same denominator:
(5 - 10 + 10 - 5 + 12 + 8)/20
Now we can add the numerators:
(20)/20
And simplify:
1
So, 1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4 = 1.
1/4 - 0.5 + 1/2 - 0.25 + 3/5 + 0.4
