Question 95624
A recipe asks for 1/4 teaspoon vanilla. A second recipe asks for 1/2 teaspoon vanilla, and the third one asks for 1/8 teaspoon vanilla. How much vanilla is needed in all three recipes. 
:
Put all three amounts over the same denominator:
We know that:
1/4 = 2/8
and
1/2 = 4/8
:
Easy to add now:
{{{2/8 + 4/8 + 1/8}}}  = {{{7/8}}} of teaspoon for all 3 recipes
