No and here’s why the main ratio is 15:12 it won’t be equivalent because 5:3 multiplied by 3 = 15:9 and 10:6 multiplied by 1.5= 15:9

Answer:

Yes it is

Step-by-step explanation:

When we simplify 15:12, we receive 5:3

Therefore, 5:3 is equvilaent to 15:12

Using this unit ratio, we can solve for other rations

For example, 5:3, the unit ratio, times 2 is 10:6

5 * 2 = 10

3*2 = 6

10, 6 = 10:6

ELEN [110]

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is 9 + x \leq 30

<em><u>Solution:</u></em>

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

<em><u>We can write a inequality as:</u></em>

\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }

9 + x \leq 30

Now moving 9 from L.H.S to R.H.S we get,

x \leq 30 - 9

On solving 30 - 9 = 21,

x \leq 21

So Sajia can sell 21 books she can sell if she comes back on sunday
