9/10. make the bottom numbers the same to add fractions. you can do that by multiplying 7/10 by 10/10.

70/100 + 20/100 = 90/100

90/100 = 9/10

you can also reduce 20/100 to 2/10.

7/10 + 2/10 = 9/10

What is the word form of 807.057 show your work
KATRIN_1 [288]

Answer:  Eight hundred seven and fifty-seven thousandths

=============================================================

Explanation:

The number 807 in word form is eight hundred seven. Be sure not to use "and" because this keyword indicates a decimal point.

So for instance, saying "Eight hundred and five tenths" would represent the number 800.5

----------------

The portion after the decimal, the 0.057, represents the value fifty-seven thousandths since that 7 is in the thousandths place value. That decimal value is the same as the fraction 57/1000.

So overall, the entire original number is read out as: Eight hundred seven and fifty-seven thousandths

Notice how I tied together the whole part 807 and the decimal part 0.057 together with the "and" keyword.

-----------------

Side note: There's not much work to show. I'm not sure what your teacher is aiming for here.

A sewing machine is at a 20% off sale. The original price was $340. How much does the sewing machine cost at a 20% off sale?
Anvisha [2.4K]

Answer:

272$

Step-by-step explanation:

Since it is at a sale of 20% off that means that we will have to subtract 100% from 20% which is 80%

Now to find the exact value, we will have to multiply 80%, or 0.80 with 340

0.80*340= 272$

Therefore our answer is 272$

                     - Hope this helped :)

-Brainliest is most appreciated :)

The Ipad that Ms. Hopham would like to buy for research is $1,299. This week it is on sale for $990, and the sales tax is 6%. Ho
Firdavs [7]

Turn the percentage into a decimal.

6% = 0.06

Multiply.

990 * 0.06 = $54.9 (sales tax)

Add.

990 + 54.9 = $1,049.40 (total price)

Best of Luck!
