<p>Please match the following and it would be better if you explain why, so confusing.</p>
<p>X is twice as many as Y.
It means X = 2Y, right?</p>
<p>If twice as many X as Y were ordered,...?
Does that mean X = 2Y or Y = 2X?</p>
<p>it means
x=2y.</p>
<p>x=2y because it takes twice as many ys to make up 1 x</p>
<p>like if I said "there are twice the number of oranges as bannanas"</p>
<p>it would mean that I have more oranges, so 2O= B</p>
<p>Think about it. x is twice y translates directly to x = 2y. That's very simple because in math, the word "is" is equivalent to "=".</p>
<p>On word problems, it's more tricky. If twice as many x as y were ordered, what does that mean? It means there are more x's than y's, right? That means you have to multiply the number of y's by some constant in order to get the same number of x's. Hence x = 2y.</p>
