last year , for every 100 million vehicles that travelled on a certain highway , 98 vehicles were involved in accidents . if 3 billion vehicles travelled on the highway last year , how many of those vehicles were involved in accidents ? ( 1 billion = 100000000 )
to solve we will set up a proportion . we know that “ 100 million vehicles is to 98 accidents as 3 billion vehicles is to x accidents ” . to express everything in terms of “ millions ” , we can use 3,000 million rather than 3 billion . creating a proportion we have : 100 / 98 = 3,000 / x cross multiplying gives us : 100 x = 3,000 * 98 x = 30 * 98 = 2,940 correct answer is c .
floor(divide(multiply(divide(multiply(multiply(3, 100000000), const_10), 100000000), 98), const_1000))
