Here’s the third one for you.
Morning Sarah and Erika, I have seen your answers, but you need to check them as they are not all accurate and you need to use RUCSAC. I won’t post your comments until later, because I want to give other people the opportunity to have a go so that I can maximise the house points I’m giving out…
1. 2,045
2.
a)6.4 = 1+ 5.4
b) 3 2/5 = 1+ 2 2/5
3. 8
Have another look at 1 and 3
Ok
1 is supposed to be 1,950
3 is supposed to be 16
I mean one is supposed to be 2,099
Actually my first answer was correct but another one could’ve been
1,950
I’m sure you have realised that it was just a small matter of RUCSAC…
Hello!
1. 1,950
2a. 6.4 = 1 + 5.4
2b. 3 2/5 = 1 + 12/5
3. (14)2 + (4)2 = 36
100 – 36 = 64
64/4 = 16
Each side is 16 cm
I think I’ve spotted my mistake (If I have one). Also, The picture is bit blurry so that may have caused some issues with the reading because I can’t really tell whether the symbol after 3 and 2/5(Q2) is a take away sign or an equals symbol.
Therefore I think my mistake may be there on question 2a, and also my wording, what I meant to say instead of ‘Each side is 16 cm’ was ‘One side is 16 cm long’.
I meant to say 2b not 2a
Have another look at 1…
1,950 and 2,045
I think it’s correct
😉
Mrs. Watson for the maths yesterday activity 1 it said that 2/3 are 67% but it is supposed to be 2/3=66%
Erika, can you think of a mathematical reason as to why 67% might be correct? There’s a concept/rule that you need to apply…
Ooooooh 😮
It has been rounded to the nearest 1%
Well done! I knew you’d get there…
