FIRST We need to make a comparison for peanuts and raisins they need. peanuts : raisins = 1 3/8 : 2/3 peanuts : raisins = 11/8 : 2/3
Simplify the ratio so it's not on a fraction form peanuts : raisins = 11/8 × 3/2 peanuts : raisins = 33 : 16 For 33 pounds of peanuts, we need 16 pounds of raisins
SECOND Calculate the need of peanuts using ratio above the sum of ratio = 33 + 16 = 49
need of peanuts = ratio of peanut/sum of ratio × sum of pounds need of peanuts = 33/49 × 245 need of peanuts = 8,085/49 need of peanuts = 165
They need 165 pounds of peanuts to make 245 pounds of trail mix
