<u><em>#10.</em></u> In order to find a ratio, all we need to do is set up a simple equation and then cross-multiply!
I'll show you !
In this case, we'll take the <u>already established ration </u><u>(14 : 8 )</u> and find the equivalent ratio where <u>7 is in place of 14 </u><u>(7: x) </u>
x will be the other table value we are looking for!
Now let's set up the equation and cross-multiply!
<u>cross multiply 14 and x, then 8 and 7 </u>
We get: 14x = 56
solve to find x!
x = 56/14
x = 4 blankets
Now let's use the ratio 7: 4 to find what goes with 16 in the table!
4x = 112
x = 112/4
x = 28 towels

<u><em>#11. : </em></u>Using the same method, I'll fill in the values of the table on #11
16 forks, 10 spoons
8 forks, 5 spoons,
48 forks, 30 spoons

<u><em>#12. </em></u>If the neighbor pays you $17 for every 2 hours of work, we need to find <u><em>how many times 2 hours goes in 8 hours of work</em></u>
We do this by dividing
8/2 = 4 times
2 hours of work goes into 8, 4 times!
Now we multiply 4 by $17 to find how much your neighbor owes you!
$17 × 4 = $68
Your neighbor owes you $68 !!!
