Question

1/10+9/100 27/100+7/10 4/5+7/10 2/3+5/9 15/24+1/6 5/9+2/27

Answer 1

Ответ:1) 1/10 + 9/100 = 10 * 1/(10 * 10) + 9/100 = 10/100 + 9/100 = (10 + 9)/100 = 19/100;

2) 27/100 + 7/10 = 27/100 + 10 * 7/(10 * 10) = 27/100 + 70/100 = (27 + 70)/100 = 97/100;

3) 4/5 + 7/10 = 2 * 4/(5 * 2) + 7/10 = 8/10 + 7/10 = (8 + 7)/10 = 15/10 = 3/2;

4) 2/3 + 5/9 = 3 * 2/(3 * 3) + 5/9 = 6/9 + 5/9 = (6 + 5)/9 = 11/9;

5) 15/24 + 1/6 = 15/24 + 4/(4 * 6) = 15/24 + 4/24 = (15 + 4)/24 = 19/24;

6) 5/9 + 2/27 = 3 * 5/(3 * 9) + 2/27 = 15/27 + 2/27 = (15 + 2)/27 = 17/27.

Answer 2

Let's simplify each of these fractions:

1. (1/10) + (9/100) To add these fractions, you need a common denominator, which is 100. (1/10) + (9/100) = (10/100) + (9/100) = (10 + 9)/100 = 19/100

2. (27/100) + (7/10) To add these fractions, you need a common denominator, which is 100. (27/100) + (7/10) = (27/100) + (70/100) = (27 + 70)/100 = 97/100

3. (4/5) + (7/10) To add these fractions, you need a common denominator, which is 10. (4/5) + (7/10) = (8/10) + (7/10) = (8 + 7)/10 = 15/10 Now, simplify the fraction further by dividing both the numerator and denominator by their greatest common factor (5). (15/10) ÷ 5/5 = (15/10) × (5/5) = (15 × 5)/(10 × 5) = 75/50

4. (2/3) + (5/9) To add these fractions, you need a common denominator, which is 9. (2/3) + (5/9) = (6/9) + (5/9) = (6 + 5)/9 = 11/9

5. (15/24) + (1/6) To add these fractions, you need a common denominator, which is 24. (15/24) + (1/6) = (15/24) + (4/24) = (15 + 4)/24 = 19/24

6. (5/9) + (2/27) To add these fractions, you need a common denominator, which is 27. (5/9) + (2/27) = (15/27) + (2/27) = (15 + 2)/27 = 17/27

So, the results are:

1/10 + 9/100 = 19/100 27/100 + 7/10 = 97/100 4/5 + 7/10 = 75/50 (which can be simplified further if needed) 2/3 + 5/9 = 11/9 15/24 + 1/6 = 19/24 5/9 + 2/27 = 17/27
