What is 90% of that same number?

A.
63

B.
68.6

C.
88.2

D.
126

Answer 1

it cant be anything less than 98 since it's asking for more

Answer 2

wait, nvm

Answer 3

Hey there!

Answer 4

'of' means multiplication

'is' means equal

Answer 5

So the question has given us:

70% of a number is 98

Let's call our number 'x'

Answer 6

So, we change the 'of' into a multiplication sign
and the is into an equal sign
and 'a number' to 'x'

we can also change 70% to 70/100 = 7/10 = 0.7

0.7x = 98

Can you solve for 'x' ?

Answer 7

Thanks Megan! You're the best! :(

Answer 8

@truwhovian11 We would all appreciate if you would cooperate! \(\Large\ddot\smile\)

Answer 9

@Comrad Thanks! I try my best! :)

Answer 11

98

Answer 12

Well, medals are not important. You learning this concept is more important.

Medals won't help you in real life, now will they?

We need you to learn this concept so that any similar question you get, you should be able to solve in 2 minutes!

Answer 16

Yes @MeganXOXO very True! We don't really need medals, all we want is to learn, and improve with our education :)

Answer 17

how would u explain that then

Answer 18

yeah i just looked at the explinations that u gave me and i also used this link to understand better im not an idiot you know Percent - Math Goodies
www.mathgoodies.com/lessons/vol4/meaning_percent.html
A percent is a ratio whose second term is 100. Percent means parts per hundred. The word comes from the Latin phrase per centum, which means per hundred. In mathematics, we use the symbol % for percent. Let's look at our comparison table again.

Answer 19

Look at all of my posts before, the asker has to answer the question I left him with.

Can you solve for 'x'?

0.7x = 98

Answer 20

Yes, so for the equation I gave you. How can we isolate 'x'? :)

Answer 21

sory that was my sis she is always trying to get people mad at me

Answer 22

I'm not mad at all \(\ddot\smile\)

Answer 23

"70% of a number is 98.

What is 90% of that same number?"

This problem might be better understood if you separate it into two parts:

1). Let the unknown number be x. Find the value of x.

2) Find "90% of x."

Done.

What have you learned from previous problems that you could apply to solving this latest one?

Write an equation now that would enable you to find the unknown number, x.

Answer 24

Exactly what mathmale said. First we need to find out 'x' is so that way we can find "90% of x."

Answer 25

MeganXOXO posted this earlier; it is appropriate!

So the question has given us:

70% of a number is 98

Let's call our number 'x' Write an equation in x that will enable you to solve for x.
