Answer 1

Given :-

• David bought 12 kg vegetables .
• From these vegetables he bought 7 kg 670 gram potatoes.
• 3 kg 42 gram onions.
• rest were tomatoes.

To Find :-

• What is the weight of tomatoes ?

Solution :-

we know that, 1 kg is equal to 1000 gm .

So,

→ Total vegetables bought by david = 12kg = 12 * 1000 = 12000gm .

and,

→ Total potatoes he bought = 7kg 670gm = 7 * 1000 + 670 = 7000 + 670 = 7670gm.

and,

→ Total onions he bought = 3kg 42 gm = 3 * 1000 + 42 = 3000 + 42 = 3042gm.

it is given that, rest were tomatoes.

Therefore,

→ weight of tomatoes = Total vegetables weight - (Total potatoes weight + Total onions weight.)

Putting values we get,

→ weight of tomatoes = 12000 - (7670 + 3042)

→ weight of tomatoes = 12000 - 10712

→ weight of tomatoes = 1288gm.

Now,

→ 1000gm = 1 kg

→ 1 gm = (1/1000) kg.

→ 1288 gm = (1/1000) * 1288 = 1288/1000 = 1 kg , 288gm.

Hence, weight of tomatoes is 1kg 288gram.

Answer 2

Given:-

• The Total Vegetables bought by David = 12kg.

• The Weight of Potatoes = 7 kg 670 gm

• The weight of Onions = 3kg 42gm

To Find:-

• The weight of the Tomatoes

Solution :-

We know the total Weight of vegetables bought by David = 12 kg.

• Converting 12 kg to grams by Multiplying 100.

• Total weight of vegetables = 12*1000=12000gm.

By this convert the Weight of onions and potatoes too.

• Weight of potatoes = 7 kg and 670gm.= 7*1000+670 = 7670gm.

• Weight of Onions = 3kg 42gm = 3*1000+42=3042gm.

• The rest is Tomatoes that is needed to be find out.

Now,

The Weight of tomatoes = Total Weight of vegetables - (Weight of potatoes + Weight of Onions )

• Weight of Tomatoes = 1200-(7670+3042)

• Weight of Tomatoes = 1288gm.

Weight of Tomatoes in kg = 1288/1000 = 1kg and 288gm.
