<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!

\frac{14}{8} = \frac{7}{x}

<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!

\frac{7}{4} = \frac{x}{16}

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 !!!

Whitch of the following options have the same value of 15 % of 20​
Gemiola [76]

Answer:

15% of 20 is 3

Step-by-step explanation:

because 15/100 can be reduced if you divide by 5 which will be 3/20. After you multiply 3/20 by 20/1. So 20*3 is 60 divided by 20 because 20*1 equals 20 you get 3.
