Resizing the Ubuntu partition to release space to install Fedora to dual boot

I have purchased Dell Vostro 3400 laptop computer that came with Ubuntu 20.04.5 LTS preinstalled on a 1TB HDD. (it has enough free space)

Output of fdisk p command in given below:

dell@dell-Vostro-3400:~$ sudo fdisk /dev/sda

Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): p
Disk /dev/sda: 931.53 GiB, 1000204886016 bytes, 1953525168 sectors
Disk model: ST1000LM035-1RK1

Ubuntu is installed and running from /dev/sda3. I want to resize /dev/sda3 and release some space so that I can install Fedora Workstation (and dual boot Ubuntu and Fedora) without losing the Ubuntu installation that came with the computer when I purchased it (as I believe it has all the appropriate device drivers, etc. and I do not want to lose them.)

What is the best way I can dual-boot this computer with Ubuntu (it came with Ubuntu) and Fedora (which I want to install) without losing the existing Ubuntu installation? (As this is a fresh machine I do not have any data here.)

When I tried to use Disks utility to resize the Ubuntu partition it says

Error unmounting filesystem 

Error unmounting /dev/sda3: target is busy (udisks-error-quarks, 14)

Backup all data (*it's easy to make a mistake & lose everything when making partition changes*) and either install Fedora (Ubuntu provides many ISOs & installers, most have an *Install Alongside* option) or resize your partitions then install. You can't resize many file-systems when they are in use, so using *live* media is the easiest way around this.

You can resize the partition with GParted from the Fedora live USB.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
