Question

Г)36:1 2/7-19,8+2 5/6

Answer 1

Г) 36:1 2/7= 28
28 - 19,8= 8,2
8,2+ 2 5/6 = 11 1/30

Answer 2

To solve this expression, we need to follow the order of operations (also known as PEMDAS or BODMAS):

1. Parentheses/Brackets
2. Exponents/Roots
3. Multiplication/Division
4. Addition/Subtraction

There are no parentheses, exponents or roots, so we move to step 3.

First, let's convert the mixed numbers into improper fractions:

2/7 = 16/49 2 5/6 = (2*6+5)/6 = 17/6

So, the expression becomes:

36:1 - 16/49 - 19.8 + 17/6

Next, we perform division, which is the same as multiplying by the reciprocal:

36:1 = 36/1 = 36

So, the expression now becomes:

36 - 16/49 - 19.8 + 17/6

Now, we need to find a common denominator for the fractions. The smallest common denominator is 294, which is the product of 49 and 6. We can convert all the fractions to have a denominator of 294:

36 - (166)/(496) - (19.8294)/294 + (1749)/(6*49)

Simplifying:

36 - 96/294 - 19.8 + 833/294

Next, we add and subtract from left to right:

36 - 0.3265 - 19.8 + 2.8299

Finally, we add and subtract to get the answer:

18.7034

Therefore, the solution to the expression is approximately 18.7034.
