Set up ratio problem

.2 oz butter / (1/15) lb jelly = x / 1 lb jelly

Then cross multiply the stuff opposite each other in the fractions... set it up as a multiplication problem

.2 × 1 = (1/15) × x

.2 = (1/15)x

Multiply both sides of equation by 15 to clear out the (1/15) fraction and get x

x = 3
