Question

Katie buys 3kg of mixed sweets .she put 10 sweets into each bag .Each sweet weighs between 6g and 8 g .Estimate the number of bags of 10 sweets that Katie can make from the 3 kg of sweets ?

Answer 1

katie can make an estimated amount of 42 bags of sweets hope this helped

Explanation:

1kg=1000g so she had 3,000g

i first started by taking 6g and 8g and adding it together to get 14g

i then took 3,000 and divided it by 14 i got 214

i then times 214 times 14 and got 2996

thats 214 time 6 and 214 times 8

i realized that if i took one of the 8 away i got 2988

which then was 213 for the 8g

3000-2988=12

that got 2 more 6g sweets

so then there was 213 8g sweets and 216 6g sweets

then at that point i added 213 and 216 together and got 429

last but not least i took 429 and divided it by 10 and got 42.9

since it asked for a estimated number of bags you can drop the .9

which then equals 42 bags of sweets
