slega [8]

Answer: $\frac{19}{6} : \frac{17}{6}$

Step-by-step explanation:

Taylor has saved $99 for a tablet. That is 45% of the cost of the tablet. How much does the tablet cost?

gayaneshka [121]

Answer:

$220

Step-by-step explanation:

Make a proportion

We know that 99 over some number (x) must equal 45%

99/x=45/100

Cross multiply

45x=9,900

Divide by 45 on both sides

x=220

So, the tablet costs $220

Hope this helps! :)
