Question

7/ 10 - 1/2 +2/5= / 15​

Answer 1

Answer:

Therefore 7/10-1/2+2/5= 9/15

Step-by-step explanation:

let the missing number be x.

7/10-1/2+2/5 = x/15

(7/10-1/2+2/5)×15 = x

(7-5+4)/10× 15 = x

6/10×15 = x

6/2×3 =x

3×3 =x

9= x

Answer 2

7/10 -1/2 + 2/5 = x/15
(7-5+4)/10 = x/15
6/10 = x/15
3/5 = x/15
3 = x/3
x = 9
