Mathematics
1 answer:
Degger [83]3 years ago
7 0

Answer:

1) -\frac{4}{1}

2)  \frac{0}{1}

3)  \frac{16}{3}

4) \frac{27}{4}

5) \frac{17}{8}

6) -\frac{7}{20}

7) \frac{39}{5}

8) -\frac{48}{5}

Step-by-step explanation:

We know that Rational numbers are those numbers that can be written in the following form:

\frac{a}{b}

Where "a" and "b" are Integers and b\neq 0

Then:

1) -4 → -\frac{4}{1}

2) 0 → \frac{0}{1}

3) Convert from  mixed number to improper fraction:

5\ \frac{1}{3}=\frac{(5*3)+1}{3}=\frac{16}{3}

Then:

5\ \frac{1}{3} → \frac{16}{3}

4) Convert from decimal number to fraction:

6.75=\frac{6.75*100}{1*100}\frac{675}{100}=\frac{25(27)}{25(4)}= \frac{27}{4}

Then:

6.75 → \frac{27}{4}

5) Convert from mixed number to improper fraction:

2\ \frac{1}{8}=\frac{(2*8)+1}{8}=\frac{17}{8}

Then:

2\ \frac{1}{8} → \frac{17}{8}

 6) Convert from decimal number to fraction:

-0.35=\frac{0.35*100}{1*100} =\frac{35}{100}=\frac{5(7)}{5(20)}= -\frac{7}{20}

Then:

-0.35 → -\frac{7}{20}

7) Convert from decimal number to fraction:

7.8=\frac{7.8*10}{1*10}\frac{78}{10}=\frac{2(39)}{2(5)}= \frac{39}{5}

Then:

7.8 → \frac{39}{5}

8) Convert from mixed number to improper fraction:

-9\ \frac{3}{5}=\frac{(9*5)+3}{5}=-\frac{48}{5}

Then:

-9\ \frac{3}{5} → -\frac{48}{5}

1: a 24 ounce box of cornflakes cost $4.59?
mestny [16]
The unit rate for the 1st one is: $0.19 / ounce

The unit rate for the 2nd one is: $0.16 / ounce

The 36 ounce box would be the better buy because it is less per ounce than the 24 ounce box

Tema [17]

Answer:

you ate 3

you paid $9.45 for the 3

to find the cost of the whole pizza you need to know how much each slice costs so

9.45 / 3 = $3.15 a slice

so each slice is $3.15 and there are 8 slices and you need to know how much they cost altogether so
