Triss [41]

Answer:

Part 1) 11/12 cups of sugar

Part 2) Each person will get 1 1/4 pounds of candy

Step-by-step explanation:

Part 1) we know that

To find out how many cups of sugar is required, adds the cups of sugar for the flour and the cups of sugar for the meringue topping

$\frac{2}{3}+\frac{1}{4}$

Find the LCD

LCD=(3)(4)=12

$\frac{2}{3}+\frac{1}{4}=\frac{4*2+3*1}{12}=\frac{11}{12} \ cups$

Part 2) we know that

To split 6 1/4 pounds of candy between them, divide 6 1/4 pounds by 5

$6\frac{1}{4}:5$

Convert mixed number to an improper fraction

$6\frac{1}{4}\ lb=6+\frac{1}{4}=\frac{6*4+1}{4}=\frac{25}{4}\ lb$

substitute

$\frac{25}{4}:5=\frac{25}{20}\ lb$

simplify

$\frac{5}{4}\ lb= \frac{4}{4}+\frac{1}{4}=1\frac{1}{4}\ lb$

therefore

Each person will get 1 1/4 pounds of candy
