6,4+1/7??????????????????????

Answer 1

32/5+1/7=229/35=6 19/35

Answer 2

It appears you want to calculate the expression 6.4 + 1/7. To do this, you can follow these steps:

Step 1: Convert the mixed number 6 4/7 to an improper fraction. 6 4/7 = (7 * 6 + 4)/7 = (42 + 4)/7 = 46/7

Step 2: Add 6.4 and the improper fraction 46/7. 6.4 + 46/7

Now, to add these two numbers together, you need to have a common denominator. The common denominator for 7 and 1 is 7. So, you need to convert 6.4 to an equivalent fraction with a denominator of 7:

6.4 = 64/10 = (64/10) * (7/7) = (448/70)

Now, you can add the fractions:

(448/70) + (46/7)

To add these fractions, you need to find a common denominator, which is 70. Then, you can add the numerators:

(448/70) + (46/7) = (448/70) + (10*46/70) = (448/70) + (460/70)

Now that you have the same denominator, you can add the numerators:

(448 + 460)/70 = 908/70

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

(908/70) ÷ 2 = (454/35)

So, the result of 6.4 + 1/7 is:

6.4 + 1/7 = 454/35

If you want to convert it back to a mixed number:

454 ÷ 35 = 12 with a remainder of 14

So, the result can be written as the mixed number:

12 14/35
