Aratio of laptops to tabelets in the stock room of a store is 13: 17. if there are a total of 90 laptops and tabelets in the stock room, how many laptops are in the stock room?

Hello, the answer to this problem is 1170/17, 68.823529, or ≈69 laptops.

To solve this, I will tell an easy thing. Ratios are the same as fractions. So, you can layout an equation like this: 13/17 = x/90. You are trying to find x, the amount of laptops. You can do a thing called cross multiply. For example, a/b = c/d. Cross multiply: a > d, b > c. In this case, cross multiplying would get you 17x = 1170.

x = 1170/17 or 68.823529

So, the answer is 1170/17, 68.823529, or ≈69 laptops.
