The ratio of computers to calculators is 59. Find the number of computers if the there are 108 calculators​
MissTica

Answer:

6,372

Step-by-step explanation:

The ratio is 59:1, meaning the new ratio is ?:108

To find the value you're searching for, multiply 108 by 59

108*59=6,372

To check your work you can divide both sides by 108 and if it is correct you should get the ratio 59:1, let's see

6,372/108=59

108/108=1

59:1... we have the right answer!

I hope i helped :)
