Q&A - P3 Math

[bluesclue]

Hi, Yes, numbers were changed as you have noticed. with 200g/ 120g for full/half glass , DS's answer for the empty glass was 40g, but teacher marked it as wrong and said answer should be 20g. :? So just wanted to find out if our understanding is correct. With CMF and your confirmation, i think 40g should be the right answer, thanks.

Hi, I just checked my DD’s workbook. Her teacher marked 40g as the correct answer.

Hi,


Can anyone help with this problem. The answer should be got using Heuristics.

Johnny had 30 ml more orange juice than Chloe at first. After Johnny drank 180 ml of orange juice, Chloe had twice as much orange juice as Johnny. How much orange juice did Johnny have at first?

TIA

Is the answer 330?

180-30=150
150+150+30=330

Is this answer correct?

Thanks HappyH,


Yes, that is the correct answer. I finally figured it out after posting it here.
