Question

(1,75+2 1/3) : (6,5 - 2/3)=

Answer 1

(1,75+2 1/3):(6,5-2/3)= (1 75/100+2 1/3):(6 5/10-2/3)=(1 225/300+2 100/300):(6 15/30-20/30)=4 1/12:5 5/6=49/12*6/35=294/420=147/210=49/70=7/10=0,7

Answer 2

First, we need to simplify the expressions inside the parentheses:

1. 1,75 can be written as 7/4
2. 2 1/3 can be written as 7/3
3. 6,5 can be written as 13/2
4. 2/3 can be left as is

Now we can substitute these values and simplify the expression:

(7/4 + 7/3) ÷ (13/2 - 2/3)

To simplify, we need to find a common denominator for the fractions in the numerator:

(21/12 + 28/12) ÷ (39/6 - 2/6)

49/12 ÷ 37/6

To divide fractions, we need to invert the second fraction and multiply:

49/12 × 6/37

294/444, which can be simplified by dividing both the numerator and denominator by their greatest common factor (which is 6 in this case):

49/74

Therefore, the final answer is 49/74.
