Question

2)3/8+5/24; 4)3/5-1/7; 6)9/17-19/68; 8)4/15-11/60.

Answer 1

2)7/12
4)16/35
6)1/4
8)1-12

Answer 2

Sure, I can help you with these calculations:

2. (3/8) + (5/24) = To add these fractions, you need a common denominator, which is 24 in this case: (9/24) + (5/24) = 14/24

Now, you can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 2: (14/2) / (24/2) = 7/12

So, 3/8 + 5/24 = 7/12.

4. (3/5) - (1/7) = To subtract these fractions, you also need a common denominator, which is 35 in this case: (21/35) - (5/35) = 16/35

So, 3/5 - 1/7 = 16/35.

6. (9/17) - (19/68) = To subtract these fractions, you need a common denominator, which is 68 in this case: (36/68) - (19/68) = 17/68

So, 9/17 - 19/68 = 17/68.

8. (4/15) - (11/60) = To subtract these fractions, you need a common denominator, which is 60 in this case: (16/60) - (11/60) = 5/60

Now, you can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 5: (5/5) / (60/5) = 1/12

So, 4/15 - 11/60 = 1/12.
