Question

8целых 5/7+4целых3/4-3целых5/8=​

Answer 1

Ответ:

$8 \frac{5}{7} + 4 \frac{3}{4} - 3 \frac{5}{8} =$

$(8 + 4 - 3) + ( \frac{5}{7} + \frac{3}{4} - \frac{5}{8} )$ =

$9 + \frac{47}{56} = 9 \frac{47}{56}$

Answer 2

To solve the expression, we need to add and subtract the given mixed numbers:

8 5/7 + 4 3/4 - 3 5/8

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

8 5/7 = (7 * 8 + 5)/7 = 61/7 4 3/4 = (4 * 4 + 3)/4 = 19/4 3 5/8 = (8 * 3 + 5)/8 = 29/8

Now we can substitute the improper fractions back into the expression:

61/7 + 19/4 - 29/8

To add and subtract fractions, we need to find a common denominator. In this case, the least common denominator (LCD) is 8:

(61/7) * (8/8) + (19/4) * (2/2) - (29/8)

Now we can rewrite the expression with the common denominator:

(488/56) + (38/8) - (29/8)

Next, we can combine the numerators:

(488 + 266 - 29)/56

Simplifying further:

(725/56)

Therefore, 8 5/7 + 4 3/4 - 3 5/8 is equal to 725/56.
