Simply the following 5 1/3 -7 5/6 + 6 1/4

lana66690 [7]

Answer:

$3 \frac{3}{4}\\$ / 3.75

Step-by-step explanation:

Step 1: Make all the mixed numbers, improper fractions:

$5 \frac{1}{3} = \frac{16}{3}$

$7\frac{5}{6} = \frac{47}{6}$

$6\frac{1}{4} =\frac{25}{4}$

In order to add/subtract fractions, they must all have a common denominator, the smallest common denominator for all these fractions is 12. And so in order to make 12 the denominator, we must now multiply all the fractions by their multiple.

$\frac{16}{3} = \frac{64}{12}$

$\frac{47}{6} = \frac{94}{12}$

$\frac{25}{4} = \frac{75}{12}$

Time to solve:

$\frac{64}{12} -\frac{94}{12} + \frac{75}{12} =$

$\frac{-30}{12} + \frac{75}{12} =$

$\frac{45}{12}$

Simplify:

$\frac{45}{12} = \frac{15}{4}$

Convert to a mixed number:

$3 \frac{3}{4}$

Hope this helps!

Kirti knows the following information from a study on cold medicine that included 60 participants: 30 participants in total rece

GalinKa [24]

The frequency table is attached.

Since there were 30 people out of the 60 that received cold medicine, that means that 60-30=30 people did not.

Since 26 people had a cold longer than 7 days, this means 60-26=34 had a cold that was less than or equal to 7 days.

14 people had a cold longer than 7 days and received medicine; this means that 26-14=12 people had a cold longer than 7 days and did not receive medicine.

30-14=16 people received medicine and had a cold less than or equal to 7 days.

30-12=18 people did not receive medicine and had a cold less than or equal to 7 days.
