I know this for sure that it's not an enlargement bc 4 is not bigger than 5 and u can do 4 divided by 5 which equals 0.8.And remember this 1 is an isometric. And I think that if it's less than 1 it's a reduction and if it's more than 1 its an enlargement. So 4 over 5 is a REDUCTION. <<<<<< that's the correct answer and also u better give me thanks -.- Please :)
