Question

3/10+1/7 9/25+2/5 1/25+3/25

Answer 1

3/10+1/7=21/70+10/70=31/70   9/25+2/5 =9/25+10/25=19/25      1/25+3/25=4/25

Answer 2

To solve these addition problems, we need to find a common denominator for each pair of fractions and then add the numerators.

Let's go through each problem:

1. 3/10 + 1/7: To find a common denominator, we multiply the denominators: 10 * 7 = 70. Then, we adjust the numerators accordingly: (3 * 7)/(10 * 7) + (1 * 10)/(7 * 10) = 21/70 + 10/70. Now that the fractions have the same denominator, we can add the numerators: 21/70 + 10/70 = 31/70.

Therefore, 3/10 + 1/7 = 31/70.

2. 9/25 + 2/5: The denominators are already the same, so we can simply add the numerators: 9/25 + 2/5 = (9 + 10)/(25) = 19/25.

Therefore, 9/25 + 2/5 = 19/25.

3. 1/25 + 3/25: Since the denominators are already the same, we can directly add the numerators: 1/25 + 3/25 = (1 + 3)/25 = 4/25.

Therefore, 1/25 + 3/25 = 4/25.

In summary:

1. 3/10 + 1/7 = 31/70
2. 9/25 + 2/5 = 19/25
3. 1/25 + 3/25 = 4/25
