  • 2 + 3 = 3 + 2
  •  Commutative Property of Multiplication.- ex. 5 × 7 = 7 × 5  
  • Associative Property of Addition.- ex.(2 + 3) + 6 = 2 + (3 + 6)  
  • Associative Property of Multiplication.- ex. (7 × 3) × 10 = 7 × (3 × 10)
  • Distributive Properties of Addition Over Multiplication- ex. 2 × (2 + 8) = 2 × 2 + 2 × 8  
  • (2 + 8) × 10 = 2 × 10 + 8 × 10

Alex787 [66]

Answer:

48% were carrot sticks.

52% were apple slices.

Step-by-step explanation:

Given that:

Total number of snacks in the tray = 25

Number of carrot sticks = 12

Number of apple slices = 25 - 12 = 13

Percent of carrot sticks = \frac{Number\ of\ carrot\ sticks}{Total\ Number}*100

Percent of carrot sticks= \frac{12}{25}*100

Percent of carrot sticks = 0.48 * 100 = 48%

Percent of apple slices = \frac{13}{25}*100

Percent of apple slices = 52%

Hence,

48% were carrot sticks.

52% were apple slices.
