riel wants to use squares to tile a floor that measures 240 cm by 300 cm what is the length of the largest square he can use
Alexxx [7]

Yung bought $4.60 worth of bubble gum. Each piece of gum cost $0.10. How many pieces of bubble gum did Yung buy?
Readme [11.4K]

<u><em>Answer:</em></u>

Yung bought 46 pieces of bubble gum for $4.6

<u><em>Explanation:</em></u>

We are given that each piece of gum cost $0.1 and that he spent $4.6 on gums

<u>To get the number of gums he bought, we will simply use cross multiplication as follows:</u>

1 piece .........................> 0.1

x pieces ......................> 4.6

<u>Therefore:</u>

x = \frac{4.6*1}{0.1}= 46 pieces of gum

Hope this helps :)
