Answer and explanation:

1. 9:12 or \frac{9}{12} or 9 to 12

It has 9 first because there are 9 lions and then 12 after because there are 12 elephants.

2. 8:16 or \frac{8}{16} or 8 to 16

It has 8 first because there are 8 giraffes and then 16 after because there are 16 otters.

3. 9:10 or \frac{9}{10} or 9 to 10

It has 9 first because there are 9 lions and then 10 after because there are 10 seals.

4. 10:12 or \frac{10}{12} or 10 to 12

It has 10 first because there are 10 seals and then 12 after because there are 12 elephants.

5. 12:9 or \frac{12}{9} or 12 to 9

It has 12 first because there are 10 elephants and then 9 after because there are 9 lions.

6. \frac{8}{6} or \frac{40}{30} or \frac{16}{12}

I just multiplied it first the first one by 2, second one by 10, and 3rd one by 4.

7. \frac{6}{7} or \frac{42}{49} or \frac{60}{70}

I just simplified it first, then I multiplied the simplified one by 6 for the second one, and for the 3rd one I multiplied the simplified by 10.

8. \frac{2}{3} or \frac{4}{6} or \frac{20}{30}

I just simplified it first, then I multiplied the simplified one by 2 for the second one, and for the 3rd one I multiplied the simplified by 10.

9. 3:4 is equivalent to 6:8, 30:40, 12:16

I multiplied it first by 2, then by 10, then by 4.

10. 5:7 is equivalent to 10:14, 50:70, 25:35

I multiplied it first by 2, then by 10, then by 5.

11. 9:2 is equivalent to 18:4, 90:20, 27:6

I multiplied it first by 2, then by 10, then by 3.

12.

a. 48

So first, the ratio we know is 5:4 which in other words is 5x:4x. We also know that there are 60 clownfish. So that means 5x = 60 --> x = 12. So then 4x has to equals 12 x 4 which is 48.

b. 36

So first, the ratio we know is 4:3 which in other words is 4x:3x. We also know that there are 48 angelfish. So that means 4x = 48 --> x = 12. So then 3x has to equals 12 x 3 which is 36.

Hope this helped! <3

Alang went to the store to buy some walnuts. The price per pound of the walnuts is $7 per pound and he has a coupon for $2.50 of
MA_775_DIABLO [31]

Answer:

$11.50 is the cost for 2 pounds of walnuts

Expression: 7p - 2.50

Step-by-step explanation:

First, create an expression to represent the cost:

7p will represent the cost, since the walnuts are $7 per pound, and 2.50 needs to be subtracted from this because of the coupon for $2.50 off

So, the expression is 7p - 2.50

Use this expression to find the price for 2 pounds of walnuts:

7p - 2.50

7(2) - 2.50

14 - 2.50

= 11.50

So, the cost with the coupon will be $11.50
