x=210

Explanation:

x/900 = 3.5/15

You would cross multiply and get;

15 xx x = 900 xx 3.5

15x = 3150

Then divide by 15 on both sides;

(15x)/15 = 3150/15

(cancel15x)/cancel15 = 3150/15

x = 3150/15

x=210

x=210

Explanation:

x/900 = 3.5/15 (Multiply both sides by 900 to isolate the variable)

x=3.5/15 *900 (15 is a factor of 900, so you can reduce 900 to 60 and 15 to 1)

x=3.5*60

x=210

Check the answer by plugging it into the original equation:

210/900 = 3.5/15
