Answer:

-1.175

Step-by-step explanation:

-4/5 + (-3/8) = -4/5 + (-3/8) = -4 · 8/5 · 8 + (-3) · 5/8 · 5 = -32/40 + (-15/40) = -32 + (-15)/40 = -47/40

The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 8) = 40. The fraction result cannot be further simplified by cancelling.

In words - minus four fifth plus minus three eighth = minus forty-seven fortieth.

Answer:

Unit price of strawberries at Grocery Mart is $ 1.495 or 150 pennies

Unit price of strawberries at Baldwin Hills Market is $ 1.33 or 133 pennies.

Step-by-step explanation:

1 dollar = 100 pennies

Given:

Cost of 2 pounds of strawberries at Grocery Mart = $ 2.99

Cost of 3 pounds of strawberries at Baldwin Hills Market = $3.99

∵ Cost of 2 pounds of strawberries at Grocery Mart = $ 2.99

∴ Cost of 1 pound of strawberries at Grocery Mart = $\frac{2.99}{2}=\$1.495=1.495\times 100\approx 150\textrm{ pennies}$

∵ Cost of 3 pounds of strawberries at Baldwin Hills Market = $3.99

Cost of 1 pound of strawberries at Baldwin Hills Market = $\frac{3.99}{3}=\$1.33= 1.33\times 100 = 133\textrm{ pennies}$

Therefore, the unit price of strawberries at each grocery store is the cost of 1 pound of strawberries. So, unit rate at Grocery Mart is 150 pennies and at Baldwin Hills Market is 133 pennies.
