Divide the number 484 into two parts in a ratio of 7 : 4. How much bigger is the first number than the second number?

132

Step-by-step explanation:

First, obtain the total of the ratio:

7+4 = 11

Then, make equations:

     and    

Next, solve:

11x = 7*484   →    11x = 3388    →    x = 308

11x = 4*484   →    11x = 1936     →    x = 176

Finally, find the difference:

308 - 176 = 132

(**If it is asking how many times bigger... 308/176 = 1.75 or   )
