The equation is \square

Studdy Solution

STEP 1

What is this asking? We need to figure out what percentage 86 is of 98, and write it as an equation without solving it. Watch out! Don't mix up the part (86) and the whole (98)!
Also, remember to express the percentage as a decimal or fraction in the equation.

STEP 2

1. Set up the percentage equation
2. Represent the unknown percentage

STEP 3

Alright, let's **break this down**!
We know that "percent" means "out of 100".
So, when we're talking about a percentage of something, we're talking about a *fraction* of that thing where the denominator is 100.

STEP 4

We can write this generally as: Part=Percentage100Whole \text{Part} = \frac{\text{Percentage}}{100} \cdot \text{Whole} This formula says that the *part* is equal to the *percentage* divided by 100, multiplied by the *whole*.
It's like taking a slice of a pie – the *whole* is the entire pie, the *percentage* is how much of the pie we're taking, and the *part* is the actual slice we get!

STEP 5

In our problem, the **whole** is $98\$98, and the **part** is 8686.
We don't know the percentage yet, so let's call it aa.

STEP 6

Now, let's **plug in** our **values** into the percentage equation: 86=a10098 86 = \frac{a}{100} \cdot 98 See how we replaced "Part" with 86, "Percentage" with aa, and "Whole" with 98?

STEP 7

This equation perfectly represents the problem: "86 is what percent of 98?" We've translated the words into math!

STEP 8

Our final equation is: 86=a10098 86 = \frac{a}{100} \cdot 98
