Who else finds math confusing? TwT

I see it as a little confusing but once you figure it out then its really straight forward from there.

like if you hate math

Looks like u got a like from meh :>

If I have 5 goldfish, and my grandma eats one, then I go fishing and somehow find 10 in a river, then my sister takes 2 of them and practices animal CPR on them, I go back to the pet store and buy 53 more, then buy 89 more. How much do i spend if each goldfish is 67 cents?

I think the cost is 257.18 dollars from getting all the goldfish and multiplying it by 1.67 I do not know if this is correct though

here's a quick tip Divide Multiply and Subtract Bring it on down then bring it on back that's all a Dividing method

Divide Subtract Multiply Bring down Repeat

how can i find rates easier

maybe work on dividing skills? i think. it seems like finding rates is similar to division in a sense

Help pls I don’t understand rates but ratios I do

Are you confused about the unit rate section? If so then the unit rate is when you try to find out how much it would be for only one item. This is credited to my teacher since I completely forgot lol

A ratio is comparing two unlike things. They are a different form of fractions.

i need help i dont understand this rates

Rates just tell you that how one quantity relates to another quantity.For example- i read 20 pages in 5 minutes(if i am reading at a constant rate) and this can be represented as 20pages/5minutes which can be simlified to give 4pages/1minute.

So i'm kind of confused and I know this isn't a part of this thing but technically fractions are ratios so why do we use them as parts of things??

Ratios are not the same as fractions. Ratios compare two numbers. For example if a bus goes 10 miles every 2 hours, it could be expressed as 10 miles:2 hours. You could also say that the bus is going 5 miles every hour, 5 miles:1 hour. In this case you divided both sides by 2. This is one way fractions and ratios are similar. However they are not the same, because a fraction is simply some number divided by another number. A ratio is a relationship between two numbers.

Review the basics of rates and try some practice problems.

What is a rate?

A rate is a ratio that compares two quantities with different units of measure.

Example of a rate:

A plane flew

765

kilometers in

3

hours.

Unit rates

A unit rate of two quantities in a ratio is the number of units of the first quantity for every

1

unit of the second quantity.

Examples of unit rates:

There are

60

minutes in

1

hour.

Jen types

42

words in

1

minute.

Finding unit rates

To find a unit rate, we divide the first quantity in a rate by the second.

Example:

A plane flew

765

kilometers in

3

hours.

765 \div 3 = 255

The plane flew at a rate of

255

kilometers per hour. We can also write the unit rate as

255 km : 1 hour

Using unit rates to solve rate problems

Let's look at an example.

Mark can make

42

birthday cakes in

7

days.

How many birthday cakes can Mark make in $5$ ‍ days?

First, we find the unit rate.

Days	Cakes
$7$ ‍	$42$ ‍
$↓ \div 7$ ‍	$↓ \div 7$ ‍
$1$ ‍	$6$ ‍

Mark makes cakes at a unit rate of

6

cakes for every

1

day.

Now, we can use the unit rate to find how many cakes Mark makes in

5

days.

Days	Cakes
$7$ ‍	$42$ ‍
$1$ ‍	$6$ ‍
$↓ \times 5$ ‍	$↓ \times 5$ ‍
$5$ ‍	$30$ ‍

In $5$ ‍ days, Mark can make $30$ ‍ cakes.

Practice

Problem 1

Frances can complete

91

oil changes in

7

days.

How many oil changes can Frances complete in $11$ ‍ days?

oil changes
