spider cracks in garage foundation and concrete ramp up into garage
Unfortunately, No. It sounds as if the installing contractor poured the concrete on a very hot day with no provisions to prevent shrinkage cracks.
Provisions against shrinkage cracks include: placing a vapor barrier (plastic)on top of the concrete to prevent excessively rapid drying and keeping this membrane wet; installing a double coating of surface sealer while the concrete is curing; saw cutting the control joints within a few hours rather than the next day; pouring in the early morning; buying a special concrete mix to prevent rapid drying; etc.
There are a lot of things which can be done to avoid shrinkage cracking, which is what I think you have since you call them spider web cracks. Your only solution now is to make the contractor break it out and re-pour the entire slab.
