Question

4,4/9:5/27 120:15/8 9/10:3/5

Answer 1

Ответ:

Пошаговое объяснение:

1) 4 4/9 ÷ 5/27 = 40/9 * 27/5 = 8/1 * 3/1 = $\frac{8*3}{1*1}$= 24/1 = 24

2) 120 ÷ 15/8 = 120 * 8/15 = 8 * 8/1 = 64/1 = 64

3) 9/10 ÷ 3/5 = 9/10 * 5/3 = 3/2 * 1/1 = $\frac{3*1}{2*1}$ = 3/2 = 1 1/2

Answer 2

Пошаговое объяснение:

4 4/9 : 5/27 = 40/9 * 27/5 = 8/1 * 3/1 = 24/1 = 24

120 : 15/8 = 120 * 8/15 = 8 * 8/1 = 64/1 = 64

9/10 : 3/5 = 9/10 * 5/3 = 3/2 * 1/1 = 3/2 = 1 1/2

Answer 3

To solve these expressions, let's go through them one by one:

1. 4/4 ÷ 9/27: To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 9/27 is 27/9. So, the expression becomes: 4/4 × 27/9 Cancel out common factors between the numerators and denominators: 1/1 × 3/1 Multiply the numerators and denominators: (1 × 3)/(1 × 1) = 3/1 = 3

2. 120 ÷ 15/8: To divide by a fraction, we multiply by its reciprocal. The reciprocal of 15/8 is 8/15. So, the expression becomes: 120 × 8/15 Cancel out common factors between the numerators and denominators: (120 ÷ 15) × (8 ÷ 1) Simplify the division: 8 × 8 = 64

3. 9/10 ÷ 3/5: Similarly, we multiply the first fraction by the reciprocal of the second fraction: 9/10 × 5/3 Cancel out common factors between the numerators and denominators: (9 ÷ 3) × (5 ÷ 10) Simplify the division: 3 × 1/2 = 3/2 or 1.5

Therefore, the solutions are:

1. 3
2. 64
3. 1.5 or 3/2
