so we can form 2 expressions here and then we can multiply cross in order to find the 100%

lets call this number X that we need to find which is the 100%

so we have: 

35%=51.8gt

100%=x

if we multiply cross, we will have 35x=51.8 * 100

35x-5180

lets divide both parts with 35 and we will have 

35x/35=5180/35

x=148
