Question

The table shows the number of apples and the total weight of the apples,number of applesweight of apples (grams)2120052016Estimate the weight of 6 apples.Type the answer in the box below.6 apples would weigh aboutgrams

Answer 1

2 apples 511 gr

5 apples 1200 gr

8 apples 2016 gr

weight / apples

511 / 2 = x / 6

x = weight of 6 apples

Cross multiply:

6 * 511 = 2 x

3066 = 2x

Divide both sides by 2

3066 / 2 = 2x/ 2

1533 = x

x= 1533

Same with the other rows:

1200/5 = x/6

6*1200 = 5x

7200 = 5x

7200/5= x

x= 1440

2016/8 = x/ 6

6*2016 = 8x

12,096 = 8x

12096/8= x

x = 1512

Average of three results: ( 1533 + 1440 + 1512 )/ 3 = 1495

6 apples would weigh about 1495 grams
