Seth at 1 - 1/2 - 1/3 = 1/6 of the sandwich.
Therefore the ratio is:
1/2 : 1/3 : 1/6
Multiply everything by 6:
3: 2: 1 D
= 125/10 + 3,75 - 2½[tex] = \frac{125}{100} + \frac{375}{100} - \frac{250}{100} [/tex][tex] = \frac{500}{100} - \frac{250}{100} [/tex][tex] = \frac{250}{100} [/tex][tex] = \frac{250}{100} \times 100\%[/tex][tex] = \frac{25.000}{100} \%[/tex]= 250%[tex]\boxed{ \red{ \boxed{\pink{\mathcal{M \frak{ ilana} \purple{ \tt01}}}}}} [/tex]
