Answer 1

Answer:

I guess the answer is 0.72

Answer 2

Answer:

8/15 + 19/30:

= LCM OF 15 AND 30 = 30

= 8 × 2 / 15 × 2 + 19 × 1 / 30 × 1

= 16/30 + 19/30

= 16 + 19 / 30

= 35 / 30

It's a improper fraction u can convert it into mixed fraction

Now,

35/30 - 4/5:

= LCM OF 30 AND 5 = 30

= 35 × 1 / 30 × 1 - 4 × 6 / 5 × 6

= 35/30 - 24/30

= 35 - 24 / 30

= 11 / 30

Actually we can do all this sum and subtraction in one time only but u didnt understand thats why I solved them separately hope you understood it
