Question

$7.4$kg is how many grams?

Answer 1

Hint: We are given the amount in kilograms. We have to convert the amount in grams. First, we will convert the kilograms into grams by multiplying the weight in kilograms by 1000. Then, write the answer by substituting the values into the formula and placing the decimal at the correct position.

Complete step by step solution:
We are given weight $7.4$ kg.
Now, we will convert the kilograms into grams by using the formula, $grams = kg \times 1000$
Convert $7.4$ kg into grams, by substituting $7.4$ in place of kg in the formula.
Therefore, on substituting we get:
$ \Rightarrow grams = 7.4 \times 1000$
On simplifying the equation, we get:
$ \Rightarrow grams = 7400.0$

Final Answer: Thus, $7.4$ kg is equivalent to $7400$ grams.

Additional Information:
Kilograms and grams are the units used to represent the weight. The symbol used to represent kilograms is kg and the symbol used to represent grams is g. The unit kilogram is greater than the grams. Therefore to obtain the value of the smaller unit, the given value must be multiplied, but if the value is required for the larger unit then the given value is divided by a specified power of 10. The order of units in decreasing order will be Tonne, Quintal, kilogram, gram and milligram. To obtain the unit in decreasing order the given value is multiplied by some power of 10, whereas to obtain the value in the unit in increasing order, the given value is divided by some power of 10.

Note:
In such types of questions students mainly make mistakes while applying the conversion formula. Students also can do mistakes while performing the calculation and placing the decimal after multiplication of the values.
