The answer would be -27 but since you aren't using negatives, A trick I use is cross the line change the sign. So it would be 1/27 I believe
All the brothers would receive 1/4 of EACH pizza. No, multiply by three, and all the brothers would get a total of 3/12 pizzas!
Hope I helped!!
252 seeds
Since there is 42 seeds in each of the 12 bags you need to multiply 42 and 12
42 × 12 = 504
So in total she has 504 seeds, now you need to split that in half by dividing 504 and 2
504 ÷ 2 = 252
Therefore she has 252 seeds left
Hope this helps! :)
