In a large bucket of screws, the ratio of slot screws to Phillips screws is 11 to 4. There are no other varieties of screws in the bucket. If there are 320 Phillips screws in the bucket, what is the total number of screws in the bucket?

Show: :: OA
1,200


We can solve this by using equivalent ratios

Let x = the number of slot screws in the bucket.

We can write: 11/4 = x/320
Cross multiply to get: (4)(x) = (11)(320)
Divide both sides by 4 to get: x = (11)(320)/4 = (11)(80) = 880

So, the bucket contains 880 slot screws and 320 Phillips screws for a TOTAL of 1200 screws

Answer: 1200
