If one serving takes 3/8 of a cup and she wants two servings, just multiply 3/8 by 2.
2 * (3/8) = 6/8 or 3/4 of a cup.
B) because if you round your numbers, -18 1/4 is -18 and 2 2/3 rounds up to positive 3
7 - 2 (7) -8
7 - 14 - 8
7-14= -7
-7 - 8 = - 15
May have messed this one up
since this is a multiplication, all the numerators are just factors of the product numerator and all denominators are just factors of the product denominator, so we can simply reorder them some, without changing the product.
