Rounding 936 to the neasrest hundred equals 900
Place Values
9 = Hundreds
3 = Tens
6 = Ones
You round up if the number next to the place value you are rounding is 5 or higher
You round it to 0 if the number next to the place value you are rounding is 4 or lower
That looks to be C i'm not sure though!
So we have ratio 5/7, and sum is 168, so clearly numbers are not 5 and 7 since 5 + 7 = 12, not 168, so ratio is 5x / 7x, where x is unknown number.
So now we can set up sum: 5x + 7x = 168
12x = 168
x = 168 / 12 = 14
So our two numbers are 5x and 7x, which are 5 * 14 = 70 and 7 * 14 = 98
So the answer is 70 and 98
G = number of girls;
b= number of boys
we know that: g= 6+2b
and that: g+b= 156 kids in total
so we may write g+b=(6+2b)+b=6+3b
but g+b= 156
so 6+3b = 156 => 3b= 156-6=150 => b=150/3=50 => b = 50 (number of boys)
g= 6+2b= 6+2 x 50= 106 => g =106 (number of girls)
