Nate and clara are drawing pictures with markers. there are 8 markers in a set. nate has 9 markers and clara has 7. what can nat

Morgarella [4.7K]

There are 8 markers in a set
nate has 9 markers
clara has 7 markers
For nate to have a set, you need:
9 markers - 1 marker = 8 markers
For clara to have a set, you need:
7 markers + 1 marker = 8 markers
Therefore, nate should give 1 marker to clara so that both have a complete set.
