Question

the ratio of tomatoes to red apples is 2:5 if there are 20 tomatoes how many red apples are there?​

Answer 1

Answer:

There were 50 apples

Step-by-step explanation:

ratio of tomatoes and apples=2:5

tomatoes =20

apples=x (let)

2/5=20/x

2*x= 5*20

2x= 100

x=100/2

x=50

There were 50 apples.

Answer 2

Answer:

50 red apples

Step-by-step explanation:

Assuming that this is a ratio of tomatoes : red apples,

You already know that you have 20 tomatoes, therefore you can get 20 : red apples

So how did we get from 2 tomatoes to 20 tomatoes? You can divide 2 from 20 (20÷2) and find that 2x10 gets you 20 tomatoes. Remember that we multiplied by 10 here.

Now that we know this, we can find the number of red apples. Since there are 5 red apples at first, we can do (5x10) and get 50. That's your answer! You can look at how this is done without the explanation at the bottom.

2 : 5 → 20 : 50

----------------

2 : 5

↓ x10 [20÷10=2]

20 : x

 x10 ↓

20 : (5x10)

20 : 50
