Question

7/10+9/10=??,3/12+50/60???

Answer 1

7/10+9/10 = 16/10 = 1 6/10

3/12+50/60 = 3/12+5/6=3/12+10/12=13/12=1 1/12

Answer 2

To add fractions, you need to have a common denominator. Let's calculate these sums:

1. 7/10 + 9/10:

Both fractions already have the same denominator, which is 10. So, you can simply add the numerators:

(7/10) + (9/10) = (7 + 9)/10 = 16/10

Now, you can simplify this fraction. Both 16 and 10 have a common factor of 2, so you can divide both the numerator and denominator by 2:

(16 ÷ 2)/(10 ÷ 2) = 8/5

So, 7/10 + 9/10 = 8/5.

2. 3/12 + 50/60:

First, simplify each fraction:

3/12 = 1/4 (by dividing both the numerator and denominator by 3)

50/60 = 5/6 (by dividing both the numerator and denominator by 10)

Now, both fractions have different denominators, but you can find a common denominator, which is 12.

(1/4) + (5/6) can be expressed with a common denominator of 12:

(1/4) + (5/6) = (3/12) + (10/12)

Now, you can add the fractions since they have the same denominator:

(3/12) + (10/12) = (3 + 10)/12 = 13/12

So, 3/12 + 50/60 = 13/12.
