1.+ 0.14 +0.23 = 0.9
2.-0.0369=0.1246

1) 0.53

2) 0.1615

Step-by-step explanation:

1) + 0.37 = 0.9

= 0.9 - 0.37 = 0.53

= 0.1246 + 0.0369 = 0.1615

1. 0.53

2.0.1615

Step-by-step explanation:

1.+0.14+0.23=0.9

let the blank space be x

here,

x+0.14+0.23=0.9

or, x + 0.37=0.9

or, x=0.9- 0.37

: . x= 0.53

2. -0.0369 =0.1246

let the blank space be x

here,

x-0.0369= 0.1246

or,x=0.1246+0.0369

: . x= 0.1615
