19 3/5 as a decimal SHOW YOUR WORK ALSO PLS!!!!

Answers

Answer:

19 3/5 = 19.6 decmial.

Step-by-step explanation:

Simplify the following:

19 + 3/5

Put 19 + 3/5 over the common denominator 5. 19 + 3/5 = (5×19)/5 + 3/5:

(5×19)/5 + 3/5

5×19 = 95:

95/5 + 3/5

95/5 + 3/5 = (95 + 3)/5:

(95 + 3)/5

95 + 3 = 98:

Answer: 98/5 = convert to decimal 19.6

Check:

Convert to a mixed number:

98/5

Divide 98 by 5:

5 | 9 | 8

5 goes into 9 at most one time:

| 1 | |  

5 | 9 | 8 |  

- | 5 | |  

| 4 | 8 |  

5 goes into 48 at most 9 times:

| 1 | 9 |  

5 | 9 | 8 |  

- | 5 | |  

| 4 | 8 |  

- | 4 | 5 |  

| | 3 |  

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:

| 1 | 9 | (quotient)

5 | 9 | 8 |  

- | 5 | |  

| 4 | 8 |  

- | 4 | 5 |  

| | 3 | (remainder)

The quotient of 98/5 is 19 with remainder 3, so:

Jerri was using a recipe for a large cake that required one-fourth of a tablespoon of cinnamon. Instead of making one large cake, Jerri decided to use the recipe to make three small cakes. How much cinnamon should she use for each of the three small small cakes?

Answers

Im pretty sure you would put 1/12 tablespoon of cinnamon in the cakes individually. You would divide 1/4 by 3. It's pretty simple. If that's not the answer I apologize dearly!

Answer:

1/12 of cinnamon

Juan and Gloria are comparing the two numbers 354.6 and 354.06. Juan says that 354.06 is equal to 10 x 354.6. Gloria says he is wrong. Do you agree with Juan or Gloria? Explain your thinking.

Answers

I agree with Gloria because Juan’s answer would be 3546.6. If you multiply any number by 10 it is moving to decimal 1 place to the right so as an example 354.06 multiplied by 10 would be 3540.6 because you moved the decimal to the right one number.

Juan is incorrect; Gloria is right. 354.06 is not equal to 10 times 354.6 as the zero only changes the decimal place value.

Gloria is accurate while Juan is mistaken. 354.6 and 354.06 do not add up to the same number. It is not possible to get a value that is 10 times the other number (354.6) by adding a zero to the decimal point (354.06).

Only the decimal place value is altered when a zero is added the actual numerical value remains unchanged. Compared to 354.6, which only has one decimal place, 354.06's additional zero after the decimal point indicates a more accurate measurement. Juan was mistaken when he said that 354.06 was equal to 10 times 354.6.

In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
