If you do long division right you get 97/8= 12.125
Whatever is in front of the comma put in place of x then solve
Answer:
The statement is correct as we will simplify the ratio of adults to children and will come down this.
25 children / 15 adults
both are multiple of 15 and will be divided to come down to 5 / 3
therefore it can be said that there were 5 children for every 3 adults.
Let me assign n a number: 3 an easy value we can work with. If we substitute it into the equation we get:
3 * (3-1). According to BIDMAS/BODMAS, we must first work out the brackets and then multiple it by the 3.
Do 3-1 = 2, 2*3 = 6 which is an even number. If we try with an even number we also get an even number:
4-1 = 3, 3*4 = 12. Even if we try this with a number like 7, 9 or 10 - we will always get an even integer, this is because, whenever we multiple an even number with an even or odd number - we always get an even number. So when we take away 1 by an even number, and multiple it with an odd number, we get even. Same applies to when we take away an odd number by 1 to get an even number and then times it by an odd number - we always get even.
