Merchants usually sell small nuts, washers, and bolts by weight (like jelly beans!) rather than by individually counting the items. Suppose a particular type of washer weighs 0.110g on the average. What would 100 such washers weigh? How many washers would there be in 100. g of washers?

1. 11g

2. 909

Explanation:

To get the Weight of a 109 washers who weigh 0.110g each we have to find the ratio of Weight of one washer to 1 washer and multiply by 100

= 100 washers x 0.110g/1 washer

= 11g

Therefore the mass of 100 washers is 11 grams

2.

Then the number of washers =

100g x 1washer/0.110g

= 909

Therefore number of washers = 909
