3 roots.

Step-by-step explanation:

One wintry week a ski town got 5 1/3 inches of snow. On monday the town got 2 3/4 inches; on tuesday it got 1 1/2 times as much;

m_a_m_a [10]

Answer: The amount of snow the town get the rest of the week is given by

$\frac{5}{24}$

Step-by-step explanation:

$\text{ Total inches of snow town got in a week }=5\frac{1}{3}=\frac{16}{3}$

$\text{ Amount of snow it is receiving on Monday}=2\frac{3}{4}=\frac{11}{4}\text{ inches }$

$\text{Amount of snow it is receiving on Tuesday}=1\frac{1}{2}=\frac{3}{2}\text{ inches }$

$\text{Amount of snow it is receiving on Wednesday}=\frac{7}{8}\text{ inches }$

$\text{Amount it is receiving in remaining week is given by}$

$\frac{16}{3}-(\frac{11}{4}+\frac{3}{2}+\frac{7}{8})\\\\=\frac{16}{3}-\frac{22+12+7}{8}\\\\=\frac{16}{3}-\frac{41}{8}\\\\=\frac{128-125}{8}\\\\=\frac{5}{24}\text{ inches }$

So, the amount of snow the town get the rest of the week is given by

$\frac{5}{24}\text{ inches }$

Ok so to find this we need to find 25% of 8 and then add that number to 8 itself. SO .25*8=2. So 2+8=10. So the answer is 10. IF you don't get it just ask and i can try to re explain
