Question

Studio532's print shop knows that it sells 5 5x7 prints for every 2 8x10 prints it sells.

One week 500 5x7 prints were sold. How many 8x10 prints were sold that week?
1. 200
2. 500
3. 5
4. 2

Answer 1

200

Explanation:

The ratios is 5 to 2 - so if you divide 500/5 = 100 then multiply 2 * 100 (the same rate) to keep the ration intact.
