2 1⁄2 ÷ 1 3⁄6 please help me with the RIGHT answer.

ycow [4]

Answer:

$1\frac{2}{3}$

Step-by-step explanation:

We want to simplify:

$2 \frac{1}{2} \div 1 \frac{3}{6}$

This is the same as:

$2 \frac{1}{2} \div 1 \frac{1}{2}$

Now let us convert the mixed numbers to improper fractions.

$\frac{5}{2} \div \frac{3}{2}$

We multiply by the reciprocal of the second fraction to get:

$\frac{5}{2} \times \frac{2}{3}$

Cancel out the common factors to obtain:

$\frac{5}{3} = 1 \frac{2}{3}$

You work 4 hours on Monday, 4.5 hours on Tuesday, 7.25 hours on Thursday, and 12 hours on Saturday. If you get paid $11.52 per h

____ [38]

Answer:

$181.44

Step-by-step explanation:

First, you convert the hours worked to minutes <em>(h)×60=(min)</em>.

4 × 60 = 240 4.5 × 60 = 270 7.25 × 60 = 435

Then, you add the minutes worked together.

240 + 270 + 435 = 945

Then, convert the total minutes worked to ours.

945 ÷ 60 = 15.75

Finally, multiply 11.52 (the pay per hour) by 15.75 (the total hours worked)

$11.52 × 15.75h = $181.44
