Answer:

0.08

Explanation:

1.7 – 2.7 – 1.34 + 4.9 – 1.48

2.7

- 1.7 (subtract 1.7 from 2.7)

--------

-1.0 [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore 1.0 is negative]

-1.0-1.34

we know that (-) (-) is (+)

therefore add -1.34 with -1.0

1.34

+ 1.0

-----------

-2.34 [since 1.34 is greater and it is negative]

-2.34+4.9

we know that (-)(+) is (-)

therefore subtract -2.34 from 4.9

4.90 ← (we put zero so that we can subtract without getting confused)

- 2.34

------------

1.56 [1.56 is positive because 4.9 is greater and it is positive]

1.56-1.48

here, digit before the decimal point is same but after decimal point .56 is greater than .48 therefore subtract 1.48 from 1.56

1.56

- 1.48

-----------

0.08

therefore, 1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08

hope it helps you!
