Question

-2 1/3:(-3 1/9):(1 1/8)​

Answer 1

Ответ:

$\frac{2}{3}$

Пошаговое объяснение:

$- 2 \frac{1}{3} \div ( - 3 \frac{1}{9} ) \div 1 \frac{1}{8} = \frac{7 \times 9}{3 \times 28} \div 1 \frac{1}{8} = \frac{3}{4} \div 1 \frac{1}{8} = \frac{3 \times 8} {4 \times 9} = \frac{2}{3}$

Answer 2

To compare the numbers -2 1/3, -3 1/9, and 1 1/8, we need to find a common denominator for the fractions and convert each number to an equivalent form with the same denominator. Then, we can compare their values.

Step 1: Find a common denominator. The common denominator for 3, 9, and 8 is 72 (LCM of 3, 9, and 8).

Step 2: Convert the numbers to equivalent fractions with the denominator 72. -2 1/3 = -2 * 72/1 + 1 * 72/3 = -144/1 + 72/3 = -144/1 + 24/1 = -144 + 24 = -120/72 -3 1/9 = -3 * 72/1 + 1 * 72/9 = -216/1 + 8/1 = -216 + 8 = -208/72 1 1/8 = 1 * 72/1 + 1 * 72/8 = 72/1 + 9/1 = 72 + 9 = 81/72

Now, the numbers are: -2 1/3 = -120/72 -3 1/9 = -208/72 1 1/8 = 81/72

Step 3: Compare the numbers. Now, we can see that -208/72 < -120/72 < 81/72.

So, the order of the numbers from least to greatest is: -3 1/9 < -2 1/3 < 1 1/8
