The equivalent ratios of mammals to birds at the zoo are;
1) 32 to 28
3) 24 to 21
We are given the ratio of mammals to birds at the zoo as; 96 : 84
<h3>Equivalent Ratios</h3>
To get the possible equivalent ratios, we need to first of all list out all the factors of 96 and 84.
- Factors of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
- Factors of 84: 1, 2, 3, 4, 6, 14, 21, 28, 42, 84.
Now, from the factors listed above, if we divide both 96 and 84 by 3, we will arrive at a ratio of;
32:28
Likewise,if we divide both by 4 we will get;
24:21
In conclusion, the only equivalent ratios are 32:28 and 24:21.

Answer:
135
Step-by-step explanation:
27 x 5 =135
680 grams.
So, it's telling us to calculate the weight, in grams, of the other rock.
So firstly,
6 of the rocks EACH have a weight of 720 grams.
So, 6 x 720 = 4320
Now save 4320 for later.
Next, we need to convert the 5 kilograms into grams.
So, 5 x 1000 = 5000
now do, 5000 - 4320 = 680.
Your final answer would then be = 680g
