to color?

Answer 1

298

Explanation:

Total pictures:

134 + 309

443

Already coloured: 145

To be coloured: 443 - 145

= 298

Answer 2

298 pictures

Explanation:

One coloring book has 134 pictures, and other one has 309 pictures. The total will be addition:

134 + 309 = 443 pictures

Rachel colored 145 of them all, so subtract 145 from 443:

443 - 145 = 298

She still has 298 pictures left.
