Answer:
15 pieces
Step-by-step explanation:
a ratio of 1:3 has 4 total parts, meaning that each part is 5.
20/3 = 15 so that means he has 5 pieces of chocolate and 15 of hard candy.
17.5x12=210
210 divided by 14=15
15x2.50=37.5
37.5
17.5 is feet so you need to divide by 12 for inches which gets 210 and you need each necklace to be 14 inches so you need to divide 210 by 14 which is 15 each necklace costs 2.50 so you multiply 2.50x15
You get 37.5
If we got 560 pounds for 800 dollars and x pounds for 1 dollar, this means that x = 560*1/800 <=> x = 56/80. Performing the calulation we get that x = 0.7
