Why This Matters Missed a lesson — or just want a refresher? This catch-up station reviews Lessons 4.1–4.3: 4.1 Understand Percent, 4.2 Relate Fractions, Decimals, and Percentages, 4.3 Estimate the Percent of a Number. Work one example from each lesson, then prove you're caught up in the mixed practice.

Start hereWords for this lesson

Read each word before you begin. Say it out loud.

Word	What it means	Example
PercentSpanish: Porcentaje	A ratio that compares a number to 100. The word means “per hundred,” and the symbol is %.	40% = 40 out of 100 = 40/100
Per hundredSpanish: Por cada cien	The meaning hidden inside the word percent: for every group of 100. It is why every percent can be written as a fraction over 100.	23% = 23/100
Decimal gridSpanish: Cuadrícula decimal	A 10-by-10 grid of 100 squares. Shading squares shows a percent directly, one square per percent.	40 shaded squares out of 100 = 40%
Part-to-wholeSpanish: Parte a todo	A comparison of one part against the whole amount. In a percent, the whole is always 100%.	The whole = 100%; the part = the percent
Greater than 100%Spanish: Mayor que 100 %	More than one whole. A percent above 100 means the amount is larger than the thing it is being compared to.	150% of the gray kitten = 1.5 times its weight
DecimalSpanish: Decimal	A number with a dot, like 0.5, that shows a part less than one.	0.75 means seventy-five hundredths

How it worksWorked example

These numbers are not on your problems. The steps are. Follow them with your own numbers.

A game download is 80 MB. 41 MB are done. About what percent is done?

Whole: 80 MB is 100%.
50% of 80 is 40 MB.
41 MB is just over 40 MB.

Answer: about 50%

Now you trySame steps, your turn

The steps are the same as the worked example. The numbers are yours. Do the work.
