Question

Eileen makes her own granola using 1 3/4 cups of oats and 2/3 cup of puffed rice. How many cups of granola does she have?

Answer 1

2 5/12 cups

Explanation:

First, turn 1 3/4 into improper fraction:

1 3/4 = 7/4

Next, Find LCG (least common multiple) of 3 and 4

Multiples of 4: 4, 8, 12, 16, 20, 24

Multiples of 3: 3, 6, 9 , 12, 15, 18

Multiply 7/4 by 3 and 2/3 by 4

7/4 x 3 = 21/12

2/3 x 3 = 8/12

Add both fractions

21/12 + 8/12 = 29/12

Reduce 29/12

29/12 = 2 5/12

So Eileen has 2 5/12 cups of granola

Hope this helps ;)
