Answer:
the teacher had 503 dominoes for the game.
Step-by-step explanation:
In order to find the answer, first you have to find the amount of dominoes the teacher purchased by multiplying the number of packs for the number of dominoes in each pack:
7*55=385
Now, since the stament indicates that the teacher already had 118 dominoes to use in the game, you have to add this amount to the number of dominoes that were purchased:
385+118=503
According to this, the answer is that the teacher had 503 dominoes for the game.
This kind of decimal is called a terminating decimal, meaning it ends rather than repeating on forever like this one: 4.5555555555...... or the fraction 2/3 when you turn it into a decimal.
871 rounded to the nearest tenth is 870
It's Rational since its a Fraction
