Answer 1

Запишите в виде неправильных дробей:

одна целая две пятых  = 7/5

три целых пять девятых = 32/9

две целых три одиннадцатых  = 25/11

8 целых одиннадцать пятнадцатых  = 131/15

девять целых  одна двадцатая = 181/20

2 задание:

62/11= 5 целых 7/11

79/18 = 4 целых 7/18

1356/226 = 6

238/14 = 17

3 задание.

а) х + 3х + 5 = 17

    4х = 17-5

    4х = 12

     х = 12:4

     х = 3

б) 3,5х + 2,2х = 4,56

     5,7х = 4,56

      х = 4,56:5,7

      х = 0,8

в) 3,2у - 2,7у = 0,6

     0,5у = 0,6

      у = 0,6:0,5

      у = 1,2

г) 3,7z - z = 0,54

     2,7 z = 0,54

      z = 0,54:2,7

       z = 0.2

Answer 2

Converting Mixed Numbers to Improper Fractions

To convert the given mixed numbers to improper fractions, we can use the following formulas: - For a mixed number *a* * b/c*, the improper fraction is (*a* * *c* + *b*) / *c*.

1. One and Two-Fifths - The improper fraction for one and two-fifths is (1 * 5 + 2) / 5 = 7/5.

2. Three and Five-Ninths - The improper fraction for three and five-ninths is (3 * 9 + 5) / 9 = 28/9.

3. Two and Three-Elevenths - The improper fraction for two and three-elevenths is (2 * 11 + 3) / 11 = 25/11.

4. Eight and Eleven-Fifteenths - The improper fraction for eight and eleven-fifteenths is (8 * 15 + 11) / 15 = 131/15.

5. Nine and One-Twentieth - The improper fraction for nine and one-twentieth is (9 * 20 + 1) / 20 = 181/20.

Excluding the Whole Part from Numbers

To exclude the whole part from the given numbers, we simply take the fractional part.

1. 62 Elevenths - The fractional part of 62 elevenths is 11/62.

2. 79 18ths - The fractional part of 79 18ths is 18/79.

3. 1356 226ths - The fractional part of 1356 226ths is 226/1356, which can be simplified to 113/678.

4. 238 14ths - The fractional part of 238 14ths is 14/238, which can be simplified to 7/119.

Solving Equations

Let's solve the given equations.

1. Equation: x + 3x + 5 = 17 - Combine like terms: 4x + 5 = 17 - Subtract 5 from both sides: 4x = 12 - Divide by 4: x = 3 - Therefore, the solution is x = 3.

2. Equation: 2.5x + 2.2x = 4.56 - Combine like terms: 4.7x = 4.56 - Divide by 4.7: x ≈ 0.9702 - Therefore, the solution is x ≈ 0.9702.

3. Equation: 3.2y - 2.7y = 0.6 - Combine like terms: 0.5y = 0.6 - Divide by 0.5: y = 1.2 - Therefore, the solution is y = 1.2.

4. Equation: 3.7z - z = 0.54 - Combine like terms: 2.7z = 0.54 - Divide by 2.7: z = 0.2 - Therefore, the solution is z = 0.2.
