70% of a number is 98.
hammer [34]
The solution is as follows:

Set up the proportion:

70% - 98
90% - x

70% / 90% = 98 / x

7 / 9 = 98 /x

(7 / 9) x = 98

x = 98 x 9/7

x = 14 x 9

x = 126

The answer is <span>D. 126.


I hope my answer has come to your help. God bless and have a nice day ahead!</span>

answer= x=20

Step-by-step explanation:

We have, 35% × x = 7

or,  

35

100

× x = 7

Multiplying both sides by 100 and dividing both sides by 35,

we have x = 7 ×  

100

35

x = 20

If you are using a calculator, simply enter 7×100÷35, which will give you the answer.
