Ratios, Proportions, and Percent

A ratio describes one quantity in relation to another. The order matters: three blue tiles for every two gold tiles is a blue-to-gold ratio of 3:2. It does not mean three tiles out of two total tiles. There are five equal-sized parts altogether, so blue tiles make up 3/5 of the collection. A fraction can express either comparison, but its denominator needs a clear meaning. A rate compares quantities with different units. If a fictional delivery drone travels 18 kilometres in three hours, its average rate is six kilometres per hour. Dividing both quantities by three creates a unit rate, which is a rate for one unit of the denominator. Keep the units attached while calculating; kilometres per hour and hours per kilometre answer different questions. Comparisons become useful when their bases match. A pack price alone does not identify the cheaper item when pack sizes differ. First calculate the price per item, then compare equivalent items. Finally, check whether differences in quality or size make the numerical comparison misleading.

FAQ

Questions people ask

Is it free?

Yes. There is no paid tier, no paywall and no subscription anywhere in MORIverse.

Are there ads?

No. MORIverse has no ad code.

Do you track me or sell my data?

We will never sell your data; that is our commitment. MORIverse's own code has no analytics or trackers. One thing is still being finished: the web host we use today sets its own bot-check cookies on every page, and those only go away when we move to our own server.

Where is my work saved?

In this browser on your device (local storage). It is not uploaded to us. Clearing your browser data clears it, so download anything you want to keep.

What doesn't it do yet?

Practice records describe local exercises, not accredited degrees or proof of professional competence. Internet references and optional videos retain their rights and sources. Live model authorship and external scholarly accreditation are not implied. Existing circuit lessons remain paused at their current eight challenges.

Is this the same as MORI University in 3D?

Yes, same world. This page is the quick overview; the walkable 3D room has all 4 tools.

Prefer to walk in?

MORI University is a real place in 3D.
