Question

3 1/3 x / 1,5 = 4 2/7 ÷ 3/14 ​

Answer 1

Ответ:

Пошаговое объяснение:

3. 1/3х : 1,5 = 4. 2/7 : 3/14

3. 1/3х = 1,5 * 4. 2/7 : 3/14

3. 1/3х = 1. 5/10 * 4. 2/7 : 3/14

10/3х = 15/10 * 30/7 : 3/14

10/3х = 15/1 * 3/7 : 3/14

10/3х = 45/7 : 3/14

10/3х = 45/7 * 14/3

10/3х = 15/1 * 2/1

10/3х = 30

х = 30 : 10/3

х = 30 * 3/10

х = 90/10

х = 9

Ответ: 9

Answer 2

x=9.

Пошаговое объяснение:

$3\frac{1}{3} x:1,5=4\frac{2}{7}: \frac{3}{4}\\\frac{10x}{3} :\frac{15}{10} =\frac{30}{7} *\frac{14}{3}\\\frac{10x}{3} *\frac{10}{15} =20\\20x=20*9\\x=9.$

Answer 3

To solve the expression 3 1/3 x / 1.5 = 4 2/7 ÷ 3/14, we can break it down step by step. First, let's convert all the mixed numbers into improper fractions:

3 1/3 = (3 * 3 + 1) / 3 = 10/3 4 2/7 = (4 * 7 + 2) / 7 = 30/7

Now, we have the equation:

(10/3) * x / 1.5 = (30/7) ÷ (3/14)

Let's simplify the right side first by multiplying by the reciprocal of the divisor:

(10/3) * x / 1.5 = (30/7) * (14/3)

Now, we can simplify the fractions on the right side by canceling common factors:

(10/3) * x / 1.5 = (10 * 2) / 7

Now, the equation becomes:

(10/3) * x / 1.5 = 20/7

Next, multiply both sides of the equation by 1.5 to isolate x:

(10/3) * x = (20/7) * 1.5

Now, calculate the right side:

(10/3) * x = 30/7

To solve for x, multiply both sides by the reciprocal of (10/3), which is (3/10):

x = (30/7) * (3/10)

Now, multiply the fractions on the right side:

x = (90/70)

You can simplify this fraction further by dividing both the numerator and denominator by their greatest common divisor (which is 10):

x = (9/7)

So, the solution to the equation is:

x = 9/7
