Identify a better estimate for the mass of the object. 

Identify the better estimate for the mass of the object. 

Which is more, 8000 grams or 8 kilograms? 

In this question we can also convert 8 kilograms to grams.
8 kilograms = 8 x 1000 grams
= 8000 grams
Now, we have to compare 8000 grams and 8000 grams. Both are the same. So, again we get that neither of them are more than the other one.
Hence, option(d) is the correct option.

5kilograms = __________grams. 

Which of these would be the lightest? 

Rashid and his 5 friends want to drink tea. They use 2 spoons of tea powder for each cup. How many spoons of tea powder is required? 

Another approach to the question could be that we can add 2 (i.e., the number of spoons of tea powder for each cup) 6 times, which is the number of people who wanted to drink tea.
Hence, number of tea spoons f tea powder required = 2+2+2+2+2+2 = 12
Thus, option(d) is the correct option.

In a market, one pineapple weighs 500gm one Banana weighs 200gm. and an apple weighs 250gm. What is the weight of 12 Bananas? 

Another approach to the question could be that we can simply add the weight of a single banana(i.e., 200 gm) 12 times since the weight of 12 bananas are required to find out.
Thus, weight of 12 bananas = 200gm + 200gm + 200gm + 200gm + 200gm + 200gm + 200gm +200gm + 200gm + 200gm + 200gm + 200gm = 2400 gm
Thus, option(d) is the correct option.
