find the sum

7/20 + (-4.8) + (-4/5) +4.9

im cluless

7/20 0.35

0.35 - 4.8 - 0.8 + 4.9

0.35 + 4.9 = 5.25

4.8 + 0.8 = 5.6

5.25 - 5.6 = - 0.35

7/20= 0.35

-4/5= -0.80
0.35-4.8-0.80+4.9=-0.80

To find the sum of the given numbers, you need to add them together. Let's break it down step by step:

1. Convert the fraction 7/20 into a decimal. To do this, divide the numerator (7) by the denominator (20):
7 ÷ 20 = 0.35

2. Add the converted fraction to the other numbers:
0.35 + (-4.8) + (-4/5) + 4.9

3. Simplify the given mixed number (-4/5) into a decimal. To do this, divide the numerator (-4) by the denominator (5):
-4 ÷ 5 = -0.8

Now, let's substitute the decimal form into the original expression and add everything together:
0.35 + (-4.8) + (-0.8) + 4.9

This simplifies to:
-4.35

Therefore, the sum of 7/20 + (-4.8) + (-4/5) + 4.9 is -4.35.
