During his versus non school football team Wade made 5 of 9 field goals he tried during his second season he made 11 of the 15 f
erastovalidia [21]

Answer:

  second season

Step-by-step explanation:

  5/9 ≈ 0.56 . . . first season

  11/15 ≈ 0.73 . . second season

The greater fraction of field goals was made in the second season.

__

You can also compare these fractions in this way:

  {5/9, 11/15}

Multiply both by 9×15:*

  {5·15, 9·11} = {75, 99}

The second fraction is larger.

_____

* The product of the denominators is the simplest number to compute as a multiple of both denominators. A smaller value can be found by removing a factor of 3, which is the GCD of 9 and 15. If both fractions are multiplied by 9×15/3 = 45, the result is {25, 33}. IMO, that's more work.

After reading 80\%80% of her e-mails in her inbox, Danette still has MM unread e-mails.
NARA [144]

Answer:   <em>The correct options are.....</em>

<em>A)   \frac{M}{1-0.8}   and</em>

<em>B)   5M</em>

Step-by-step explanation:

Suppose, the number of e-mails Danette had in her inbox before she started reading was X.

Percentage of read emails is 80%, so the number of read emails = (\frac{80}{100}*X)=0.8X

<u>Thus, the number of unread emails</u> = X-0.8X=X(1-0.8), <u>which is given as</u> M.

So, the equation will be........

X(1-0.8)=M\\ \\ \Rightarrow X=\frac{M}{1-0.8} (Answer: 1) \\ \\ \Rightarrow X=\frac{M}{0.2}\\ \\ \Rightarrow X=(\frac{1}{0.2})M=5M (Answer: 2)

Thus, the expressions which could represent the number of e-mails Danette had in her inbox before she started reading are:  \frac{M}{1-0.8} or 5M

Estimate the answer by rounding each fraction to the nearest whole number and then adding.
Natasha_Volkova [10]

Answer:

24

Step-by-step explanation:

<u>First, we round the fractions. </u>

If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.

7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.

1/8 is less than half so we round down and remove the fraction so we are left with 10.

<u>Then we add.</u>

14+10=24
