Connor gathered dry ingredients to make a large pan of brownies. He mixed1 1/4 cups of sugar, 2 2/3 cups of flour and 1 1/6 cups
sveta [45]

Answer:

5\frac{1}{2}

Explanation:

1. Find a common denominator for the three fractions. A common denominator is a number all three numbers divide into evenly. The lowest common denominator for 4, 3, and 6 is 12.

2. Find the numerators. This can be done by multiplying the current numerators by however many times the old denominator goes into the new denominator.

4 goes into 12 3 times

3 goes into 12 4 times

6 goes into 12 2 times

1 x 3 = 3

2 x 4 = 8

1 x 6 = 6

So, the fractions become:

1\frac{3}{12} + 2\frac{8}{12} + 1\frac{2}{12}

3. Add the numerators of the new fractions and keep the denominator the same.

4 \frac{13}{12}

4. Convert the improper fraction to a mixed number.

1 \frac{1}{12}

5. Finally, add the whole numbers.

1 + 4 = 5
