Answer
1½ cups of red onions will be able to make 6 batches of salsa.
Step-by-step explanation
Let the number of batches that 1½ cups of red onions can make be x
¼ cup of red onions = 1 batch of salsa
1½ cups of red onions = x batches of salsa
We can write a mathematical relationship by cross multiplying
(¼) (x) = (1½) (1)
Before we proceed, note that
¼ = 0.25
1½ = 1.5
So,
(¼) (x) = (1½) (1)
(0.25) (x) = (1.5) (1)
0.25x = 1.5
Divide both sides by 0.25
(0.25x/0.25) = (1.5/0.25)
x = 6 batches
Hope this Helps!!!
