Answer 1

Пошаговое объяснение:

17/8*2 5/8=5  4/9*х

17/8*21/8=49/9*х

357/64=49/9*х

459/448=х

х=1.03

Answer 2

Ответ:

х=459/448 или х≈1,03

Пошаговое объяснение:

17/8*2 5/8=5  4/9*х

17/8*21/8=49/9*х

357/64=49/9*х

459/448=х

Answer 3

To solve the expression, let's first convert all mixed numbers to improper fractions:

1 7/8 = (8 * 1 + 7) / 8 = 15/8 5 4/9 = (9 * 5 + 4) / 9 = 49/9 2 5/8 = (8 * 2 + 5) / 8 = 21/8

Now, we have the expression as:

(15/8) : х = (49/9) : (21/8)

To solve for "х," we can use the rule for dividing fractions:

(a/b) : (c/d) = (a/b) * (d/c)

Using this rule, we can rewrite the expression as:

(15/8) * (8/21) = (49/9)

Now, simplify:

15 * 1 = 15 8 * 21 = 168

So, the equation becomes:

15/168 = 49/9

Now, cross-multiply to solve for "x":

15 * 9 = 135 49 * 168 = 8232

Therefore:

x = 135/8232

Now, we can simplify this fraction:

x = 5/306
