Step 1. Type it into a Google search box or calculator. (You need to use a calculator anyway.) The result is
3177 4/9.
If you're doing this according to the Order of Operations, you do the multiplication and division left to right. This means the first calculation you do is
255/6 = 42.5
Next, you multiply by 672
42.5*672 = 28560
Then divide by 9
28560/9 = 3173 3/9
You continue by doing the division
37/9 = 4 1/9
And finish by adding the two results
3173 3/9 + 4 1/9 =
3174 4/9_____
If you're doing this by hand, you can recognize the first term as the product of two fractions, so is the product of numerators divided by the product of denominators.
(255*672)/(6*9)
Using your knowledge of divisibility rules, you can do the division 672/6 to simplify this to
(255*112)/9
Now, the first term and the second term have the same denominator, so you can add the numerators before you do the division.
(255*112 + 37)/9 = (28560 + 37)/9 = 28597/9
You end up having to do only two simple divisions, rather than 3 of them.
28597/9 = 3177 4/9
Answer:
Step-by-step explanation:
first it would be easier to change2 1/3 into an improper fraction.
so 2 x 3 + 1 = 7 so it would be 7/3
5/6 x 7/3 = 35/18
and 35/18 is definitely not 10/3
when you multiply fractions, times the numerator together, and the denominator together

She needs to buy two 1 gallon cans
high 9 ft=1side=9ft
2 sides=18ft
140-18=122 122/2=61 the other side is 61ft
Area 61x9=549 squared ft
549/300=1.83 cans
