Answer:
5:7
Step-by-step explanation:
A pet store has two types of betta fish which is red and blue
She noticed that 7 out of the 12 beta fishes are red
This means that there are 7 red beta fishes and 5 blue betta fishes
Therefore the ratio of blue betta fish to red betta fish is
= 5:7
If you would like to know the value of the 2.9% tax, you can calculate this using the following steps:
2.9% tax of $46 shoes = 2.9% * 46 = 2.9/100 * 46 = $1.334
If you would like to know what is the whole price you have to pay for the shoes (including the tax), you have to add $46 and $1.334:
$46 + $1.334 = $47.334
Try to start by reading the manual it came with. If it didn't come with a manual, then your teacher in school will teach you how to use it for specific commands. Otherwise it's just like using a regular calculator but with the ability to do more things, what do you need to know on it?
The system of equations has one solution
1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price
