Answer:
The question is incomplete; the complete question is:
Hevesh needs 75 dominoes for a design. She weighs a bag of dominoes and it’s 14 oz. Each domino weighs 7/25 oz. How many dominoes are in the bag? Will she have enough?
There are 50 dominoes in a bag, which won't be enough for Havesh's design
Step-by-step explanation:
Havesh has been said to need 75 dominoes for a design.
She weighs one bag full of dominoes and obtained 14oz as the weight.
She also found out that one domino weighed 7/25oz.
Hence, to get the number of dominoes in the bag, we divide the weight of the total dominoes in a bag by the weight of one domino i.e.
14 ÷ 7/25
The division sign (÷) changes to multiplication (×), this effects a change in the numerator and denominator of the divisor (7/25) i.e.
14 × 25/7
= 2 × 25
= 50
Hence, there are 50 dominoes in one bag.
Since, Havesh needs 75 dominoes for her design, it means that one bag of dominoes will not be enough for her as it will remain 75 - 50 = 25 dominoes to complete.
She will need more than a bag to complete her design, specifically, one and a half (1 1/2) bag.
