Mary has 16 3/4cups of flour she made one dessert that used 1 1/3cups and another than used 2 5/12cups how much flour does mary have left after making the two desserts?

13

Step-by-step explanation:

Mary has 16 3/4 cups of flour

She uses 1 1/3 cup and 2 5/12, we add the amount she uses together

1 1/3 + 2 5/12

4/3 + 29/12 = 16 + 29 / 12

=45/12 = 15/4

Amount left = amount has - amount used.

16 3/4 = 67 / 4

Amount left = 67 / 4 - 15 / 4

=52 / 4 =13

The answer to your question is 2, 1/2, 1, 2

Step-by-step explanation:

a) 3² 4³ 2⁻¹ / (3 4)² = (3²)(4²) 4 (2⁻¹) / (3 4)² = (3  4)² 2² 2⁻¹ / (3  4)² = 2

b) 2⁴ 3⁵ / (2 3)⁵ = 2⁴ 3⁴ 3 / (2 3)⁵ = (2 3)⁴ 3 / (2 3)⁵ = 3 / 2 3 = 1/2

c) 3⁻³ 2⁻³ 6³ / (4°)² = (3 2)⁻³ 6³ / 1² = 6⁻³ 6³ = 1

d) (3 2)⁴ 3⁻³ / 2³3 = 3⁴2⁴ 3⁻³ / 2³3 = 3 2 / 3 = 2
