Hello... I'm teacher Reynan
you must know the conversion of kilograms (kg) into grams (g) before you solve this problem.
since in 1 kg we have 1 000 grams
we can easily solve the missing numbers which is 100 g to make 1 000 grams and equal to 1 kg.
Answer : 100 grams (g)
let x -be the number of grams to be added by 500g+200g+200g which is equal to 1kg
let 1kg = 1000 grams
equate the equation using this formula:
1000g= 500g +200g+200g+x
find the value of x by transposition
1000g-500g-200g-200g= x
100g=x
so there,the answer is 100g.
solution :-
As we know that
1 kg = 1 000 grams
from question we get
1000g - 900g =100g missing number or gram
we can easily solve the missing numbers
1 kg = 1 kg Ans.
answer is 100 grams, because 1 kilogram is equal to 1000 grams.
GIVE ME A FEEDBACK.
