ans

Answer 2

Answer:

9/10

Step-by-step explanation:

just we have to add 2 fractions (7/10+1/5)

Find the least common denominator or LCM of the two denominators:

LCM of 5 and 10 is 10

For the 1st fraction, since 5 × 2 = 10,

1

5

=  

1 × 2

5 × 2

=  

2

10

Likewise, for the 2nd fraction, since 10 × 1 = 10,

7

10

=  

7 × 1

10 × 1

=  

7

10

Add the two fractions:

2

10

+  

7

10

=  

2 + 7

10

=  

9

10

So, 1/5 + 7/10 = 9/10
