Select all ratios equivalent to 15:5.<br> 9:3<br> 6:2<br> 3:1
natali 33 [55]

Answer:

All three.

Step-by-step explanation:

All three of these ratios are equivalent to 15:5. Here's how:

Let's look at the first ratio, 9:3. Did you notice something common? 3 x 3 = 9. 9/3 = 3. 5 x 3 = 15. 15/3 = 5. Both of these numbers are divisible by 3,  so these ratios are equivalent.

Second. 6:2. 2 x 3 = 6. 6/3 = 2. 5 x 3 = 15. 15/3 = 5. See the similarity? The same applies to the next problem, number three, although it does slightly differentiate.

Third, 3:1. See, here, since the ratio is smaller than the problem, we can't multiply, since this ratio is smaller than the original number. But, it's still the same thing. A ratio is a number that compares a value to another value. This means that 3:1 is 3 compared to one. Now, let me clarify. 15:5. 3:1. These are the exact same values, except they are just written in a different form, and simplified. Since 5 x 3 = 15, we know that we can divide 15 evenly by 5, which makes it 3, and divide 5 evenly by 5, which equals one. So here we have our answer for the third problem. 5:1.

Ratios are basically division, except simplified. Every single ratio problem works this way. Once you get the hang of it, it's immensely easy. Hope this helped!

<u><em>Answer:</em></u>

<u><em>$55.93 or rounded up is $56</em></u>

<u><em>Division</em></u>

<u><em>First, we would divide 15.98 by 2 to see how many dollars would a bag cost.</em></u>

<u><em>15.98 divided by 2 = $7.99</em></u>

<u><em>Multiplication</em></u>

<u><em>Then, we would multiply by 7 to see how may dollars would it cost for 7 kg bag</em></u>

<u><em>7.99 times 7 = 55.93</em></u>

<u><em>Round-up</em></u>

<u><em>If we round it up, we get $56.</em></u>
