Answer 2

Answer:

41/10, is the answer, explanation is given below.

Step-by-step explanation:

firstly +(-4/5) and +(-5/2) will be converted to -4/5 and -5/2.

then As per law of simplification of fractions, lcm of denominators should figured out,

so lcm of 8,2,5,8,2,5 will be 40. so now we take 40 as denominator and divide the fraction denominator with 40 and whatever you get multiply be the fraction numerator.

For example. 40/8×5, 40/2×9, 40/5×-4, 40/8×7, 40/2×-5, 40/5×7.

After all this, we get = 25+180-32+35-100+56/40

for easiness we can do that take all +signs together and -signs together.

25+180+35+56-32-100/40

at last we get 164/40

= 41/10 or 4.15.

please like hope it helps you.
