First you want to make the denominators the same. You do this by multiplying them. However, whatever you do you to the denominator, you must also do to the numerator:

$\frac{8x6}{5x6}$ - $\frac{1x5}{6x5}$ = $\frac{48}{30}$ - $\frac{5}{30}$ = $\frac{43}{30}$

Now reduce to simplest terms:

$\frac{43}{30}$ =1 $\frac{13}{30}$

It takes 16 sections of carpet to cover 1 classroom floor. Tyler wants to know how many sections of carpet are needed for 6 clas

katovenus [111]

If 1 classroom uses 16 sections, then 6 classrooms would use :
6 * 16 = 96 sections

and 14 classrooms would use : 14 * 16 = 224 sections

explain whether rounding or compatible numbers gives a closer estimate for the product of 48 times 123 equals 5904

SIZIF [17.4K]

The compatible numbers (numbers you can easily use and calculate in your head) for 48 and 123 would be 50 and 100. 50 x 100= 5,000. Rounding would be 50 and 120. 50 x 120= 6,000. So rounding would provide a closer estimate.
