[Insert generic name here] is trying to bake a yellow cake because [reasons]. This recipe will make one whole cake.

3(1)/(4)\ cups\ of\ flour\n 2(1)/(2)\ teaspoons\ of\ baking\ soda\n (1)/(2)\ teaspoon\ of\ salt \n 1(3)/(4)\ cups\ of\ sugar \n (2)/(3)\ cup\ of\ butter \n 2\ eggs\n 1(1)/(2)\ teaspoons\ of\ vanilla\ \n 1(1)/(4)\ cups\ of\ milk

He wants to make three cakes instead of one. How much of each item should be used in the new (scaled-up) recipe?

3(1)/(4)*3=9(3)/(4)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ cups\ of\ flour\n 2(1)/(2)*2=4(2)/(2)=4+1=5\ \ \ \ \ teaspoons\ of\ baking\ soda\n (1)/(2)*3=(3)/(2)=1(1)/(2)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ teaspoons\ of\ salt \n 1(3)/(4)*3=3(9)/(4)=3+2(1)/(4)=5(1)/(4)\ cups\ of\ sugar

(2)/(3)*3=(6)/(3)=2\ \ \ \ \ \ cups\ of\ butter\n 2*3=6 \ \ \ \ \ \ \ \ \ \ \ \ eggs\n 1(1)/(2)*3 = 3(3)/(2) = 4\frac{1}2\ teaspoons\ of\ vanilla\ \n 1(1)/(4)*3=3(3)/(4)\ \ \ \ \ \ \ \ cups\ of\ milk

I don't know exactly how your teacher wants you to write out the work, but I have it pretty simple there. It's not like math is tailored to a specific process; any sort of reasonable work should do.

Good luck!

0.00005893 = 5.893 x 0.00001 = 5.893 x 10^-5  
n= ^-5
