Answer:
He doesn't have enough plant to feed strawberry 2 more times and tomato 1 more time
Step-by-step explanation:
On sunday , sheldon bought 4 1/2 kg of plant food. He uses 1 2/3 kg on his strawberry plants and used 1/4 kg for his tomato plants. b. Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time. He will use the same amounts of plant food as before. How much plant food will be need? Does he have enough left to do so.
Total food bought = 4 1/2 kg
Strawberry feed = 1 2/3 kg
Tomato feed = 1/4 kg
Total food used on Sunday = Strawberry + tomato
= 1 2/3 + 1/4
= 5/3 + 1/4
= (20+3)/12
= 23/12 kg
Total food remaining after Sunday = Total food bought - used food
= 4 1/2kg - 23/12kg
= 9/2 - 23/12
= (54-23)/12
= 31/12 kg
= 2 7/12 kg
Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time.
Strawberry = 2 × 1 2/3kg
= 2 × 5/3
= 10/3 kg
Tomato = 1 × 1/4kg
= 1/4 kg
Total food needed to feed strawberry two more times and tomato 1 more time
= 10/3 kg + 1/4 kg
= (40+3)/12
= 43/12 kg
= 3 7/12 kg
He will need 3 7/12 kg of food
He has 2 7/12 kg of food left
Therefore, he doesn't have enough plant to feed strawberry 2 more times and tomato 1 more time
