1.)3,71+(-13,6)+(-71/100)== -10,6
2.)-0.109+86 1/4/+(-80891/1000=134,25

Answer 2

1) To solve the expression 3.71 + (-13.6) + (-71/100), we can follow these steps:

Step 1: Add 3.71 and (-13.6). The result is -9.89. Step 2: Add -9.89 and (-71/100). To add a decimal number and a fraction, we need to convert the decimal to a fraction. -9.89 can be written as -989/100. Now we can add -989/100 and -71/100, which gives us -1060/100. Step 3: Simplify the fraction -1060/100. The numerator (-1060) and denominator (100) have a common factor of 20. By dividing both the numerator and denominator by 20, we get -53/5.

Therefore, the result of the expression 3.71 + (-13.6) + (-71/100) is -53/5 or -10.6.

2) Let's solve the expression -0.109 + 86 + 1/4 - (-80 + 891/1000) step by step:

Step 1: Simplify the expression inside the parentheses. -80 + 891/1000 can be written as -80000/1000 + 891/1000. To add fractions, we need a common denominator, which is 1000 in this case. Both fractions already have the same denominator, so we can add the numerators: -80000 + 891 = -79109. The result is -79109/1000.

Step 2: Add up all the terms in the expression: -0.109 + 86 + 1/4 + (-79109/1000).

Step 3: Convert -0.109 to a fraction. It can be written as -109/1000.

Step 4: Find a common denominator for all the fractions, which is 1000.

Step 5: Add the numerators: -109 + 86000 + 250 + (-79109). The result is -79108.

Step 6: Simplify the fraction -79108/1000. The numerator (-79108) and denominator (1000) have a common factor of 4. By dividing both the numerator and denominator by 4, we get -19777/250.

Therefore, the result of the expression -0.109 + 86 + 1/4 - (-80 + 891/1000) is -19777/250 or approximately -79.108.
