Answer 1

Answer:

Weight of 1 pair earrings = 12.5 grams

Step-by-step explanation:

According to the information provided in the question it is given as

Total weight of 65 pairs of similar earrings= 8 12.5 grams

We need to find  what is the weight of each pair of earrings

As we all know that in a pair there are two numbers

Hence 65 pairs = 65 x 2 = 130 numbers

Here we make an equation for solving this question as follows

Let us assume  x is the weight of 1 pair

65 pairs = 812.5 grams

1 pair= x

Now by simple cross multiplication we get the answer

[tex]65=812.5\\ 1= x[/tex]

[tex]65 x= 812.5\\ x= \frac{812.5}{65} \\ x= 12.5 grams [/tex]

so weight of 1 pair earrings = 12.5 grams

Proof :

65 x 12.5 =812.5
