How many times longer is the baby alligator than the baby gecko?

The aligator is 3/4 foot the gecko is 2/15 foot.

If the babies have the same length ratio as the parents:

\({\color{blue}\frac{A}{G}=\frac{3}{4}:\frac{2}{15}=\frac{45}{8}=5\frac{5}{8} } \)

Then the alligator baby would be 5 5/8 times as big as that
Geckobaby
I do not dare!

4÷ 8/9− 1/2 =

\({\color{blue}4:\frac{8}{9}-\frac{1}{2}=4\times\frac{9}{8}-\frac{1}{2}=\frac{9}{2}-\frac{1}{2}=4}\) !

what is 8.25% of 160

\({\color{blue}160\times 8.25 \% = 160\times \frac{8.25}{100} = 13.2}\)    !

How do you write a mixed fraction?

An example  \(3\frac{5}7{}\)

klick  Σ LaTeX  (Top, last line)

remove:   x = {-b \pm \sqrt{b^2-4ac} \over 2a}

Please enter: 3\frac{5}{7}

klick  OK   ⇒   \({\color{blue}3\frac{5}{7}}\) !

Hello Guest!

I can not figure out how to do this can someone.

{(214-125/5)-{954/6)-4*7})

{(214 - 125 / 5) - {954 / 6) - 4 * 7})
The brackets are mixed.
Try a logical arrangement:

(214 - 125 / 5) - {954 / 6 - 4 * 7}

= (214 - 25) - {159 - 28}

=189 - 131

= 58

Perhaps it is true (but only maybe!)

Hello Guest!

A truck can be rented from Company A for

​$120 a day plus​ $0.40 per mile. Company B charges​ $50 a day plus​ $0.90

per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

\(\$ 120 + x\times \$0.40/mile=\$50+x\times\$0.90/mile\)

\(x\times(\$0.40-\$0.90)/mile=\$50-\$120\)

\(x=\frac{\$70}{\$0.50/mile}\)

\({\color{blue}x= 140\ miles}\)

\({\color{blue}The \ rental \ costs \ for \ 140 \ driven \ miles}\)

\({\color{blue} \ are \ the \ same \ for \ both \ offers.}\)
