Answer:
You both together can make 48 desserts in 20 minutes.
Step-by-step explanation:
It is a proportion.
5 minutes = 12 desserts
20 minutes = x desserts
Now let's form a proportion and find the value of "x"
5/20 = 12/ x
Cross multiplying, we get
5x = 240
Dividing both sides by 5, we get
x = 240/5
x = 48
You together can make 48 desserts in 20 minutes.
Hope this will helpful.
