Answer 2

Let's simplify these fractions step by step:

1. 1/10 + 7/100: To add these fractions, you need a common denominator. In this case, it's 100. So, you can rewrite 1/10 as 10/100: 10/100 + 7/100 = 17/100

2. 21/100 - 1/100: These fractions already have a common denominator, which is 100. You can simply subtract them: 21/100 - 1/100 = 20/100 = 1/5

3. 15/24 + 3/8: To add these fractions, you need a common denominator. In this case, the common denominator is 24, which is the least common multiple of 24 and 8. You'll need to adjust the fractions accordingly: (15/24) + (9/24) = 24/24 = 1

So, the results are:

• 1/10 + 7/100 = 17/100
• 21/100 - 1/100 = 1/5
• 15/24 + 3/8 = 1
