Question

(-4целых 1\5×2целых 1\7)×1\18

Answer 1

1) - 4 1/5 * 2 1/7 = - 21/5 * 15/7 = - 315/35 = - 9

2) - 9 * 1/18 = - 9/1 * 1/18 = - 9/18 = -1/2

Ответ: - 1/2

Answer 2

To solve the expression (-4¾ × 2⅛) × 1/18, we need to perform the operations step by step. First, let's convert the mixed numbers into improper fractions:

-4¾ = -4 - ¾ = -4 - (3/4) = -16/4 - 3/4 = -19/4

2⅛ = 2 + ⅛ = 2 + (1/8) = 16/8 + 1/8 = 17/8

Now we can substitute these values back into the expression:

(-19/4 × 17/8) × 1/18

To multiply fractions, we multiply the numerators together and the denominators together:

(-19/4) × (17/8) × (1/18) = (-19 × 17 × 1) / (4 × 8 × 18) = -323/576

Therefore, (-4¾ × 2⅛) × 1/18 equals -323/576.
