What is 3 1/3 -1 1/2 as a fraction?
eduard

Answer:

11/6

Step-by-step explanation:

<u>Step 1:  Convert to Improper fractions</u>

3 1/3 = 3*3/3 + 1/3 = 9/3 + 1/3 = 10/3

1 1/2 = 1*2/2 + 1/2 = 2/2 + 1/2 = 3/2

<u>Step 2:  Make common denominators</u>

10/3 * 2/2 = 20/6

3/2 * 3/3 = 9/6

<u>Step 3:  Subtract</u>

20/6 - 9/6

11/6

Answer:  11/6

if you want to buy a shirt that cost 18.99 but you have 20% off coupon and the tax is 7%. how much does the shirt cost
dusya [7]

20% off means you pay 80% of the price so you multiply by 0.8, and 7% tax means you multiply by 1.07

Resulting cost = 18.99*0.8*1.07 = 16.26

Hope this helps let me know if im wrong!

Alekssandra [29.7K]

Answer:

GJI = 242.67

Step-by-step explanation:

A circle is 360 degrees

GI + GJI = 360

The arc length is the same as the angle when it is at the center

117.33 + GJI = 360

GJI = 360 - 117.33

GJI = 242.67
