we have

radius sphere A

$rA=24\ cm$

radius sphere B

Divide the diameter by

$rB=(42)/(2) =21\ cm$

we know that

the scale factor is equal to

$scale\ factor=(rB)/(rA) \\ \\ scale\ factor=(21)/(24)$

Simplify divide by
numerator and denominator

$scale\ factor=(7)/(8)$

therefore

the answer is

The factor is
