Subtract the measurements: 40 pecks 6 quarts − 20 pecks 7 quarts a.20 pecks 7 quarts b.20 pecks 4 quarts c.19 pecks 6 quarts d.19 pecks 7 quarts

Option D. 19 pecks and 7 quarts.

Step-by-step explanation:

Subtract the measurements : 40 pecks 6 quarts - 20 pecks 7 quarts.

There are 1 peck = 9 quarts

40 x 9 = 360  quarts

360 + 6 = 366 quarts

There are 1 peck = 9 quarts

20 x 9  = 180

180 + 7 = 187

366 - 187 = 179

179 quarts is your answer

Now convert it in to pecks and quarts divided by 9

179 ÷ 9 = 19.888 ≈ 19.9  19 pecks 9 quarts close to Option D.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
