Questions :
Simplify: (1 2/5 + 2.8) − 1 3/5
Options :
- 2.6
- 2.7
- 2.85
- 2.9
correct answer : a)
Explanation :
Convert the mixed fractions into decimal form:
1 2/5 = 7/5 = 1.4
1 3/5 = 8/5 = 1.6
Now substitute the values:
(1.4 + 2.8) − 1.6
= 4.2 − 1.6
= 2.6
Therefore, the simplified value is 2.6. Hence, the correct answer is option (a). The values 2.7, 2.85, and 2.9 are incorrect because they do not satisfy the given expression.
