Basically you would break down the numbers let's say you start off with 48, 8 times 6 gives you 48 what can go into 8, 2 and 4 then you say what can go into 4 which is 2 and 2 then break down 6, 3 an 2 basically you break it down all the way until you get the prime numbers
The jar has 138 grams of zinc.
<u>Solution:</u>
Given that , In a certain chemical reaction, the ratio of zinc to copper is 3 to 16.
A jar of the chemical contains 736 grams of copper.
We have to find how many grams of zinc does it contain
Let "n" be the grams of zinc needed for 736 grams of copper
Now, we know that,
16 grams of copper ⇒ 3 grams of zinc
Then, 736 grams of copper ⇒ n grams of zinc
So, by criss cross multiplication,
16n = 3 x 736
16n = 2208
n = 138
Hence, the jar has 138 grams of zinc.
