Oh sunday sheldon bought 4 1/2 kg of plant food,he used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.How many kg of palnt food did sheldon have left?

Step 1

We add up the kg of plant food that he used

He used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.

The total amount of plant food that he used = 1 2/3 kg + 1/4 kg

Lowest Common Denominator 12

1 + (2/3 + 1/4)

1 + (8 + 3/12)

1 11/12 kg of plant food

Hence he has used 1 11/12 kg of plant food

Step 2

The amount of plant food that he had left is calculated as:

Amount of plant food Sheldon bought - Amount of plant food he used

Amount of plant food Sheldon bought = 4 1/2 kg

The amount of plant food that he had left = 4 1/2 kg - 1 11/12

4 - 1 + (1/2 - 11/12)

Lowest common denominator = 12

3 + ( - 5/12)

= 2 7/12 kg

Therefore, the kg of plant food that sheldon had left = 2 7/12 kg

the answer is two. hope this !
