6/5 × 3/4 -10 шестнадцатых +348 480 шестнадцатых

To solve this expression, we need to first convert 6/5 and 3/4 to have a common denominator.

6/5 = 24/20

3/4 = 15/20

The expression now becomes:

24/20 x 15/20 - 10/16 + 348480/16

Next, multiply the fractions and simplify:

(24 x 15) / (20 x 20) - 10/16 + 348480/16 = 360 / 400 - 10/16 + 348480/16 = 9/10 - 10/16 + 348480/16

Now, let's find a common denominator to combine the fractions:

9/10 = 72/80

10/16 = 50/80

The expression becomes:

72/80 - 50/80 + 348480/16

Finally, combine the fractions:

(72 - 50)/80 + 348480/16 = 22/80 + 348480/16 = 11/40 + 348480/16 = 11/40 + 21780 = 11/40 + 21780/1 = (11 * 1 + 21780 * 40) / (40 * 1) = (11 + 871200) / 40 = 871211 / 40

So, the final result is 871211/40.
