Do a part over whole fraction
98% is a part of 100%
343 is a part of the number of mules who were surveyed in an unknown quantity.
You can set what you know into two proportions equal to each other:
![(98)/(100) =(343)/(x)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/16s4wagpye3gfiqp5ouhb7yjwdla00cg57.png)
***x is the unknown value
Now you can cross multiply/butterfly
98x = 34300
Isolate x by dividing 98 to both sides of the equation
98x/98 = 34300/98
x = 350
This means that a total of 350 mules were surveyed
Hope this helped!
