The correct option is B 3
Say:
On the screen, we have a spoon and a pin that are measured with the help of paper clips.
We have to find out how much longer the spoon is from the pin, in terms of length measured using paper clips.
Steps:
Let us begin by counting the number of paper clips for the spoon and see how long it is. It is 7 paper clips long.
Let us now calculate the length of the pin. It is 4 paper clips long.
To find out how much longer the spoon is from the pin, we will do 7−4 which is equal to 3.
That means, the spoon is 3 paper clips longer than the pin.
Hence, the correct answer is Option D.
