Answer:

<u>Q/ Draw a line ; Ans; </u>

$\frac{9}{5} —>1 \frac{4}{5}$

*explain ; We put the 5 in the denominator and 5 multiply 1 + 4 so equal 9 so the choice 9/5 .

Ans; 7/3—> 2 1/3

*explain ; We put the 3 in the denominator and 3 multiply 2 + 1 so equal 7 so the choice 7/3 .

Ans; 12/10 —> 1 1/5

*explain; simple (12 and 10) ÷ 2 so equal 6/5

We put the 5 in the denominator and 5 multiply 1 + 1 so equal 6 so the choice 6/5 =12/10 .

$\frac{12 \div 2}{10 \div 2} = \frac{6}{5} = 1 \frac{1}{5}$

<u>Q/ Compare the fractions;Ans;</u>

$\frac{2}{3} < \frac{14}{6}$

* explain; 2/3 = 0.66 and 14/6=2.33 so 2.33 greater from 0.66 so 14/6 greater from 2/3 .

$\frac{3}{8} < \frac{8}{3}$

* explain; 3/8 = 0.375 and 8/3=2.666 so 2.666 greater from 0.375 so 8/3 greater from 3/8 .

$2 \frac{1}{6} > \frac{5}{9}$

* explain; 2 1/6 —> We put the 6 in the denominator and 6 multiply 2 + 1 so equal 13 so equal 13/6

13/6 = 2.16 and 5/9=0.55 so 2.16 greater from 0.55 so 13/6 = 2 1/6 greater from 5/9 .

<u>Q/Add; Ans;</u>

$\frac{7}{8} + \frac{5}{8} = \frac{7 + 5}{8} = \frac{12}{8} = \frac{3}{2}$

$\frac{1}{9} + \frac{2}{3} \\ \\ \frac{1}{9} + \frac{6}{9} = \frac{ 1+6 }{9} = \frac{7}{9}$

<u>Q/Subtract; Ans;</u>

$\frac{6}{7} - \frac{4}{7} = \frac{6 - 4}{7} = \frac{2}{7}$

$\frac{7}{3} - \frac{2}{9} \\ \\ \frac{21}{9} - \frac{2}{9} = \frac{21 - 2}{9} = \frac{19}{9}$

<u>Q/ Multiply;Ans;</u>

$\frac{1}{5} \times \frac{1}{2} = \frac{1}{10}$

$\frac{2}{3} \times \frac{3}{8} = \frac{6}{24} = \frac{1}{4}$

<u>Q/Divide;Ans;</u>

$\frac{3}{4} \div \frac{2}{5} \\ \\ \frac{3}{4} \times \frac{5}{2} = \frac{15}{8}$

$\frac{8}{9} \div \frac{1}{3} \\ \\ \frac{8}{9} \times \frac{3}{1} = \frac{24}{9} = \frac{8}{3}$

I hope I helped you^_^

PLEASE HELP ME ASAP!!!!! I ONLY HAVE 2 ATTEMPTS LEFT!!!!

Answer:

m∠1 = 105°

m∠2 = 75°

Step-by-step explanation:

Lines a and b are parallel.

1. Angles 1 and 75° are the same side angles when two parallel lines a and b are cut by transversal t.

The same side angles add up to 180°, so

m∠1 + 75° = 180°

m∠1 = 180° - 75°

m∠1 = 105

2. Angles 2 and 1 are supplementary (add up to 180°), then

m∠1 + m∠2 = 180°

m∠2 = 180° - 105°

m∠2 = 75°

when Apple sells their iPads they increase the price $50 from what it cost then to actually make the iPads one Apple Store sold

Anvisha [2.4K]

First things you have to do is figure out how much they increased the iPads by:

$50 • 10 = $500

They increased the iPad price by $500.

Subtract the total amount from the iPad price:

$5,000 - $500 = $4,500

The actual price of 10 iPads, without an increase is $4,500

Now divide that by 10 to get the amount for one iPad:

$4,500 ÷ 10 = $450

One iPad actually costs $450 to make.

Teresa needs to save $25.50 to go to the movies this weekend. She currently has $3. If Teresa makes $7.50 an hour babysitting, h

Aleksandr [31]

If we set the amount of hours she needs to babysit as x, his word problem can be shown as:

3+ 7.50x = 25.50

Now we can just solve for x

25.50-3= 22.50

22.50/7.50 = 3

Therefore she has to babysit 3 hours
