9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>
Answer:
The model is made in a<u> 1:40 ratio
</u>
Step-by-step explanation:
How many times is 4 multiplied to be equal to 160?
4(x) = 160
X = 160 / 4
<u>X = 40</u>
The proportion, rate, and ratio are almost the same.
They represent the correspondence between the parts and the whole since they all express a binary relationship between the quantities, that is, objects, people, tablespoons.
If the ratio is 1: 2 it could be read that for every 1 there are 2.
For example 1: 2 cups; For every cup of something there are 2 cups of something else.
In this case, 1:40; For every inch of the model, there are 40 feet in the playground.
140 cm = 55.1181102 inches,
<span>55.1181102 (divided by 12 to get feet) = 4.6 feet </span>
<span>so you are a little over 4 feet 7 inches.</span>
