Two batches of soup will serve 8 people. Lonnie needs to make enough soup for 120 people. If the recipe calls for 2 onions for one batch, how many onions will Lonnie need?

Answer :

luana
2 batches - 8 people 
2 onions - 1 batch
x onions- 120 people
From proportion
y batches-120 people
2batches - 8 people
after cross multiplication
120/8=15*2=30 batches 
x onions - 30 batches
2 onions- 1 batches
30 batches *2=60 onions
6417
"2 batches of soup will serve                            8 people."
Then x batches of soup will serve                         120 people         
120.2 = 8.x
x = 30 batches of soup will serve 120 people.

"2 onions for                1 batch"
Then y onions for         30 batches                                                          
30.2 = 1.y
y = 60 onions
